Traits

Innate SpellcastingThe oni's innate spellcasting ability is Charisma (spell save DC 13). The oni can innately cast the following spells, requiring no material components: At will: darkness, invisibility 1/day each: charm person, cone of cold, gaseous form, sleep

Magic WeaponsThe oni's weapon attacks are magical.

RegenerationThe oni regains 10 hit points at the start of its turn if it has at least 1 hit point.

Actions

MultiattackThe oni makes two attacks, either with its claws or its glaive.

Claw (Oni Form Only)Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.

GlaiveMelee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) slashing damage, or 9 (1d10 + 4) slashing damage in Small or Medium form.

Change ShapeThe oni magically polymorphs into a Small or Medium humanoid, into a Large giant, or back into its true form. Other than its size, its statistics are the same in each form. The only equipment that is transformed is its glaive, which shrinks so that it can be wielded in humanoid form. If the oni dies, it reverts to its true form, and its glaive reverts to its normal size.

How to actually run it

Tactics

The stat block tells you what it can do. This tells you what to do with it.

1Multiattack: The oni makes two attacks, either with its claws or its glaive.

2It casts spells — read its spell list before the fight and hold a Counterspell or a way to break concentration.

3With a 30 ft. flying speed it can stay out of melee reach; a party with no ranged answer will chase it all fight.
