Defense (boost).png

The Defense Boost is a feature of some buildings and items to increase the defense value of units defending the city by a certain percentage. The defense boost can also be activated from the Friends Tavern by paying for it with Tavern Silver.

The defense boost only benefits the defending units, offensive units will not be affected. To increase the stats of the offensive units players may use the attack boost.

When having multiple defense boosts, either from buildings or from items, those percentages are stacked. Then the unit's base defense value is increased by the result.

The following sources increase the defense values of the players troops when they are used for defending. This applies only for the City Defense when the player is attacked by another player of their neighborhood.

Great Buildings

Some of the Great Buildings offer a Fierce Resistance or Advanced Tactics bonus, which beside increasing the defense value also increases the attack value of the defending units.
