You summon the spirits of ancient heroes that take the form of up to three Humanoids of challenge rating 5 or lower and appear in unoccupied spaces you can see within range. Each Humanoid disappears when it drops to 0 hit points or when the spell ends.
The Humanoids are friendly to you and your companions. Roll initiative for the summoned Humanoids as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you), as long as the commands don’t violate their alignment. If you don’t issue any commands to the Humanoids, they defend themselves from hostile creatures but otherwise take no actions.
The GM has the Humanoids’ statistics.
