Magic Resistance. Oshundo has advantage on saving throws against spells and other magical effects.
Multiattack. Oshundo makes two Chilling Grasp or Arcane Bolt attacks.
Chilling Grasp. Melee Spell Attack: +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: +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.
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.
