Multiattack. Steel Crane makes three attacks.

Force Strike. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) force damage, and if the target is a creature, it must succeed on a DC 15 Constitution saving throw or be stunned until the start of Steel Crane's next turn.

Whip. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 6 (1d4 + 4) slashing damage or, if the target is a creature, Steel Crane can grapple the target instead (escape DC 15). Steel Crane can't make attacks with the whip while using it to grapple a creature. Anytime on his turn, he can release a creature grappled by the whip (no action required).

Heal Self (Recharges after a Long Rest). Steel Crane regains 2d8 + 4 hit points, and all levels of exhaustion end on him.

Deflect Missile. In response to being hit by a ranged weapon attack, Steel Crane deflects the missile. The damage he takes from the attack is reduced by 1d10 + 10. If the damage is reduced to 0, Steel Crane catches the missile if it's small enough to hold in one hand and Steel Crane has a hand free.

Slow Descent (3/Day). When Steel Crane falls, he can slow his descent, taking no damage from the fall.
