Dominate Person is a level 5 enchantment spell. This spell allows spellcasters to force a humanoid to temporarily fight as an ally.
Description
Make a humanoid fight alongside you. Every time the creature takes damage, it makes a WisdomSaving throw against your domination. Allies cannot be dominated.
As of Patch 5, the level 10 Enchantment Wizard feature Split Enchantment will allow targeting 2 humanoids with Dominate Person, but will not result in dominating both, even with failed saves, as the second instance of domination ends the effect of the first.
Dominated
Saving throw against your domination. Allies cannot be dominated.
