Guild Battlegrounds

Guild Battlegrounds (GBG) is a feature which was introduced to the game by InnoGames on 14th November 2019. It is envisioned as an alternative guild feature to Guild vs Guild. It is also an attempt of bridging the gap between mobile and desktop players. However, it is not a replacement of Guild vs Guild, as both will exist side by side.

The only requirements for participating in Guild Battlegrounds are that the player must be a part of a guild and has to have researched the Military Tactics technology.

In a nutshell, all guilds who want to participate will be match-made into various battlegrounds. Each battleground is its own map that holds five to eight guilds and will last for 11 days. Within each battleground, the participating guilds will fight for victory by holding as many provinces as possible for as long as possible.

On the 9th December 2021 the Guild Battlegrounds got an update which introduced a second battleground map every second season which comes with its own set of rewards.

Gameplay

There are two battleground maps which will be alternating every battleground season (meaning once one map has been played the other will follow). In addition to being alternating, the map will also be the same for the entire world. The Volcano Archipelago map is the old original map, while the Waterfall Archipelago map is the new one introduced later.

Accessing the Map

Once the player has researched the Military Tactics technology and is a part of a guild, the Guild Battlegrounds can be accessed by selecting the Battleground building located at the north-east corner of the city. The player will then be transported to an island nation, which contains a fixed number of provinces.

Overview

Five to eight guilds battle each other for 11 consecutive days. Each guild starts at the edge of the battleground map with a province, which cannot be taken from them, called the headquarter (HQ). The distance between neighboring guild headquarters will be about the same. From there, the guilds can start conquering adjacent provinces. Every guild member can click on an eligible province and either perform a fight or a negotiation. These fights and negotiations will always match the era of the player who performs it.

After completing the fight or negotiation, the member will provide his guild with one or more advances, which will be visualized as a conquest flag on the target province. The first guild to accumulate enough advances will gain control over the given province, whereas all other guilds that tried to conquer it as well will lose half the advances that they have made towards that province.

Gaining Provinces

Guilds can only attack provinces which are adjacent to one of their own. With each won encounter, advances are gained. The guild with the highest amount of advances in a province will have its “conquest flag” displayed in the respective province. Other guilds having advances in a province have their shield displayed next to the conquest flag of the leading guild. The closer the guild with the highest progress is getting to conquering the province, the higher the strength of the displayed flag will be.

When a certain amount of advances is reached, the province will get taken over. The amount of advances needed depends on the league - higher leagues needing more advances.

League:	Copper	Silver	Gold	Platinum	Diamond
Advances needed:	40	70	100	130	160

A province that was just taken will be under lock-down for four hours, giving the new owner some time to get victory points or build sector buildings. During lock-down, no guild can progress their conquest flag further in that province.

Attacking & Negotiating

Any guild member can tap on a province to bring up its window. There will be two options for earning points available there - Attack and Negotiate. Both the opposing army for attacking and the goods required for negotiation will depend on the player's age (similar to Guild Expeditions). Negotiating an encounter will bring more advances than attacking as more time and resources are required for it. Attacks give 1 while solving a negotiation gives 2, therefore with low Siege Camp (SC) support negotiating might be a better option, even for fighters (with low attrition). When negotiating, you can face 4, 5 and 6 option negotiations.

Show/Hide Negotiation Table for 6 option negotiations

The 4 or 5 options are relatively simple, but here is a table that should help others doing negotiations with the 6 option. For the first turn, you always put 5 different resources, and based on the result of the first turn, the table shows what gives the higher chance for solving the negotiation in 3 turns. Since there is no 4th turn in GBG, you have to solve the negotiation in 3 turns, so based on the result of the 2nd turn, it should be straightforward what resources you should pick. It's very likely you will have to guess, face a coin flip situation.

This table was made by the help of the FoE-Helper addon. Will plan to add the missing results, but based on a medium-size sample, these were the patterns I faced. The table is sorted by chance, and within each row the result is sorted in red-yellow-green order. You need to find the row that matches your pattern in this order.

Explanation for the colors:

• red - Resource is not correct.
• yellow - Resource is correct, but wrong place.
• green - Resource is correct.
• grey - Another resource, not used in the first turn.

The numbers represent different resources. You need to take the alignment into account, such as where do you place a specific resource, under 2 reds, or 1 red and 1 yellow!

Chance to Win	Result pattern of 1st turn (red-yellow-green)	Result of 1st turn / Options for 2nd turn
100%	0-2-3
79%	3-1-1
74%	3-0-2
73%	1-2-2
71%	3-2-0
67%	2-1-2
62%	2-2-1
56%	1-3-1
46%	2-3-0
44%	2-0-3
32%	1-4-0

Defending

There is no means of directly defending the acquired provinces. The only way of defending your guild's provinces will be by trying to take the provinces of the attacking guild before they take yours. In this case, if the opposing guild loses all adjacent provinces they also lose all advances that they have made towards your province.​

Winning Battlegrounds

The leader board of a battleground gets dictated by victory points, which are automatically earned by every guild once per full hour. The amount of victory points gained depends on the provinces that a guild holds. Provinces towards the center of the battleground map provide many more points than those at the edge of the map. The player can see the rankings for their specific battleground at any time, listing all participating guilds, the number of provinces held, their current gain in victory points per hour, their current amount of victory points and the rewards of every rank.

Completion

Upon completion of each battleground, there will be a 3-day break for the guilds to rest, collect their rewards and make new preparations. The guild score will then be updated.

Victory Points

The Victory Points are particularly used to measure and count the points towards the completion of the current battleground; thus they are reset at the start of every new round. Each province, besides the HQ, that a guild holds will provide victory points every hour. The magnitude of points provided by a province increases the closer it is to the center of the map.

Provinces give a certain amount of victory points per hour and the values are randomized for every battleground and every season:

• Provinces of the innermost ring (ring coordinate 1), may give between 100 and 200 Victory Points per hour.
• Provinces of the second ring (ring coordinate 2), may give between 60 and 120 Victory Points per hour.
• Provinces of the third ring (ring coordinate 3), may give between 40 and 80 Victory Points per hour.
• Provinces of the outermost ring (ring coordinate 4) may give between 10 and 40 Victory Points per hour.

Attrition

Whenever a player successfully completes a battle or a negotiation (in the context of a Guild Battleground) they will build up Attrition. This is a percentage value that directly affects the (attack and defense) boosts of the defending armies and the difficulty level of the negotiations that the player will face.

So at some point, performing attacks or negotiating will become unfeasible as the defending armies become too strong and the negotiations become too complex or too expensive. However, attrition resets to 0% each day (midnight server time).

Currently, the attack penalty and the negotiation factor will stay the same after reaching level 150 attrition.

League System

According to a guild's performance, they can climb the ladder to join the highest leagues. New guilds start off in the Copper league and can advance to Silver, Gold, Platinum and Diamond league. Upon introduction of the Guild Battlegrounds on a server, all existing guilds will get assigned to a league depending on various parameters of the guild that reflect the guilds activity.

A guild's league will be shown in the global rankings and also affects the magnitude of their battleground rewards. Performing great in a battleground will increase the guild's league rating while performing poorly will move the guild down a league.

League Points

Formerly known as MMR - Match Making Rating.

The guild's league is dependent on the guild's League Points.

The guild's League Points can reach from 0 to 1000.

League	League Points Range
Copper	0-100
Silver	101-350
Gold	351-650
Platinum	651-900
Diamond	901-1000

When the Guild Battlegrounds were introduced, every existing guild's League Points were roughly estimated depending on various factors like guild size, activity in Guild vs. Guild (GvG), activity in the Guild Expeditions, guild level, and so on. Hereby the League Points were intentionally estimated too low, so no guild started out in the diamond league and only a few started in platinum.

Every guild founded after the introduction of the Guild Battlegrounds will start in the copper league with 0 League Points.

After the initial League Points estimation, the League Points will only change depending on the guild's ranking in the respective battleground.

Depending on the placement and the number of opponents in the battleground, the guilds' losses or gains of League Points when the battleground concludes seem to be:

Place	8 Guilds	7 Guilds	6 Guilds	5 Guilds
1st	+175	+150	+125	+100
2nd	+125	+100	+75	+50
3rd	+75	+50	+25	0
4th	+25	0	-25	-50
5th	-25	-50	-75	-100
6th	-75	-100	-125	-
7th	-125	-150	-	-
8th	-175	-	-	-

Should a guild be pulled into a battleground of a higher league, that guild would receive a bonus of 50% on the League Points gain if they place in the upper half and receive a discount of 50% on the League Points loss in case they place in the lower half. The same applies for guild's fighting in their very first season.

As can be seen from the League Points range for the leagues and the gains and losses of League Points for every battleground, it might take a couple seasons to rank up or down if the guild repeatedly places only slightly above or below the middle. Even when placing first or last, it might take two or three seasons before a change in league can be observed.

Match Making

The Battlegrounds match making algorithm takes the guilds in the order of their League Points and puts them into battlegrounds together. That way all guilds in a battleground will have similar League Points values.

In the case a league has no guilds, there will be no battlegrounds for that league. In the case a league has fewer then five guilds (left), the guilds with the highest League Points of the next league down will be pulled up into the higher league's Battleground.

Example

In the beginning there might be the case that there is only a single platinum guild and eight gold guilds. In that case, the four of the gold guilds with the most League Points will get paired with the only platinum guild in a platinum level battleground. They will receive platinum level rewards for the season and they will have higher gains and fewer risks regarding the change in League Points depending on their placement. The other four gold guilds will be paired with the silver guild with the most League Points to play in a gold level battleground. The silver guild will gain the before mentioned bonuses.

Province Buildings

Each province has up to three slots for province buildings. Each province building affects its own or adjacent provinces in a special way. For instance, they may make taking an adjacent province easier or they may make it harder for the enemies to take the province.

Any member with the "Battleground Constructor" role can access provinces of their own guild to decide which of the available province buildings they want to build. However, each province building takes time to complete and will cost guild treasury goods to be constructed.

The costs depend on the building. The costs given below are the total amount of goods which is split over three random goods. The goods can be from any era represented in the guild at the start of the battleground - bronze age players hereby will be counted as iron age players. The more players are of a specific era, the more likely it is that a needed good is from that era. The respective goods and specific amounts are randomised for every building, guild, province and battleground.

The building time can be shortened by using 50 diamonds. The same building can be built multiple times per province if the province has multiple slots for province buildings.

If a province gets taken over, each province building that was being built there has a 50% chance to be destroyed. The remaining buildings will benefit the new owner.​

	Name	Properties	Costs	Building Time
	Outpost	This province requires +10% advances to be conquered.	500	5 hours
	Fortress	This province requires +30% advances to be conquered.	3,000	6 hours
	Decoys	If an enemy fights or negotiates to conquer this province, there is a chance of 15% that this enemy will suffer double the amount of attrition.	500	4 hours
	Traps	If an enemy fights or negotiates to conquer this province, there is a chance of 45% that this enemy will suffer double the amount of attrition.	3,000	5 hours
	Watchtower	If members of the owning guild of this province advance into adjacent provinces, they have a 8% chance to not increase their attrition level.	500	1 hour
	Siege Camp	If members of the owning guild of this province advance into adjacent provinces, they have a 24% chance to not increase their attrition level.	3,000	2 hours
	Banner	This province generates 10% more victory points.	250	30 min
	Statue	This province generates 30% more victory points.	1,500	1 hour
	Palace	This province requires +30% advances to be conquered. This province generates 75% more victory points.	12,000	6 hours
	Militia Barracks	unknown - not implemented (yet)

Battleground Rewards

When a battleground ends, guilds and guild members may obtain various rewards, which depend on placement and map:

• Prestige Points for the ranking according to your current guild rating (League Points )
  • 18 prestige per League Point
• Guild Power according to placement within a battleground
• Fragments for the Statue of Honor awarded to guild members, if battleground was placed on Volcano Archipelago map
• Fragments for the The Great Elephant awarded to guild members, if battleground was placed on Waterfall Archipelago map

A guild needs 40 advances or more total to receive a reward.

Loot

Apart from rewards for your guild, there are also individual rewards; whenever you contribute an advancement (by fighting or negotiating), there is a chance to loot some Forge Points, Goods, a military unit or even Diamonds. This chance will be higher in case the advancement is made by negotiating. Looted Forge Points will be added to the player's Forge Points bar.

The Volcano map and the Waterfall map has the same chance to get a reward. But the chances for certain rewards and some rewards themselves is different between the maps.

The chances given below are counted occurrences so far. Note that the chances for the Loot Distribution will not add up to 100% for each league, because the 50% for the Statue of Honor Fragments are the only officially confirmed chance.

Summary

• New battleground starts every 14 days
• 5 to 8 guilds of the same league fight on the battleground for 11 days if a higher league has not enough members, guilds from lower leagues may be pulled into the higher league battleground - they will have a chance for higher winnings and also have less loss in League progress if they come out in the lower half of the ranking.
• Winning / losing a battleground affects the league your guild is playing in, and the rewards you get after the 11 days
• A guild's league dictates which opponents they will face on their next battleground
• Victory is decided by gaining victory points from holding provinces on the battleground map
• To conquer provinces, guild members perform battles or negotiations
• Provinces can be customized with province buildings, which are unique boosts for this new feature (not yet implemented)
• All guild members that researched the technology Military Tactics (Iron Age) will be able to provide a valuable contribution for their guild
