You call forth an elemental spirit. It manifests in an unoccupied space that you can see within range. This corporeal form uses the Elemental Spirit stat block. When you cast the spell, choose an element: Air, Earth, Fire, or Water. The creature resembles a bipedal form wreathed in the chosen element, which determines certain traits in its stat block. The creature disappears when it drops to 0 hit points or when the spell ends.
The creature is an ally to you and your companions. In combat, the creature shares your initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you). If you don't issue any, it takes the Dodge action and uses its move to avoid danger.
Lesser elementals might be conjured with mere gestures and words, but you seek to summon a more powerful being. For that, the summoning place and components must align with the element: like with like with like. The words you chant change as well, drawing from different parts of the Primordial tongue to craft a welcome unique to the being you summon.
