Perhaps we could reduce the damage settings for DK. This is to balance a DOT implement to fatigue and ley upon hitting the opponent.
Provided an arc does not have full mana, the ley increases having stepping into a pool. Perhaps DK would drain (curse) its opponents/victims by taking some Fatigue and Ley (along with reduced DOT HP, again from its original settings).
Perhaps to heal a curse, one steps into their shrine.
Is this possible?
