Gem of Corruption

Hitting an enemy applies a mark that can stack up to 5 times. Marked enemies will emit an explosion when no new stack of mark has been added for 3 s or if the enemy dies. The explosion deals 5 Shroud damage in a 1m radius. Each stack adds 0,5m and 50% of the base damage to the explosion. The value 5 is a base value that scales with the weapon's level.
