Skulls are a way of obtaining rewards when playing a match by damaging the enemy Warlord. The more damage you deal the more Skulls you earn and the higher the rewards!

Up to 3 Skulls can be obtained in a match, one when the opponent's health reaches 20 or lower, a second one when their health reaches 10 or lower and a third one when you win the match (either by reducing the opponent health to 0 or if the opponent surrenders).

The rewards obtained at the end of a match will generally depend on the number of Skulls achieved. Moreover, the Daily Skulls missions will reward you with Campaign Points upon reaching certain milestones each day.
