Ideal Elves

Spell "Song of Peace" - the unit cannot attack or cast spells for one turn. Here's another idea: a leshy – half-tree, half-plant, half-spirit; a protector and guardian of the forest; it hates everything corrupted by magic (mages, necromancers, demons, orcs) – its damage, speed, and initiative increase; if the enemy units are not on this list, the leshy finds peace, and its defense, morale, and hit points increase.
