Traits

Magic Resistance.

Oshundo has advantage on saving throws against spells and other magical effects.

Actions

Multiattack.

Oshundo makes two Chilling Grasp or Arcane Bolt attacks.

Chilling Grasp.

Melee Spell Attack Roll: +8 to hit, reach 5 ft., one target. Hit: 14 (4d6) cold damage, and Oshundo regains 14 hit points if the target is a creature.

Arcane Bolt.

Ranged Spell Attack Roll: +8 to hit, range 120 ft., one target. Hit: 28 (8d6) force damage.

Thundering Blast (Recharge 5-6).

Oshundo emits a wave of domineering energy in a 60-foot cone. Each creature in that area must succeed on a DC 16 Intelligence saving throw or take 22 (4d8 + 4) thunder damage and have the stunned condition for 1 minute. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Reactions

Negate Spell (3/Day).

Oshundo targets one creature it can perceive within 60 feet of itself that is casting a spell. If the spell is 3rd level or lower, the spell fails, but any spell slots or charges aren't wasted.

Oshundo casts one of the following spells, requiring no material components and using Intelligence as the spellcasting ability (spell save DC 16):

At will: dancing lights, detect magic, detect thoughts, disguise self, mage hand, prestidigitation

1 each/day: dominate monster, globe of invulnerability, invisibility, modify memory, plane shift (self only), wall of force
