The domain skill [Shadow Rain] has been used.
As a warrior that uses darkness yourself, you are unaffected by the decrease in stats that is applied to normal users. Instead you are given a +10% increase in all stats while under the effect of [Shadow Rain]. For normal users if they dwell under the rain for too long they themselves will be possessed by the darkness and become a minion for the rest of their lives. [Shadow Rain] will stay in effect until the monster who summoned it is destroyed.
