Zugzwang

1st-level enchantment

Casting Time: 1 action

Range: 40 ft.

Components: V, S, M* (a king piece from a chess game that is worth at least 1 gp)

Duration: Instantaneous

You see the battlefield as a chessboard and direct it as such. As an action, you target one creature within 40 ft. of you and command that creature to move their movement speed and make one melee attack at a target creature if there is a creature within range of their melee attack.

That creature must succeed on a Charisma saving throw or be forced to carry out that command. The spell fails if you command it to enter obviously harmful territory, like off of a cliff or into lava.

Creatures immune to the charmed condition are immune to this spell.
