Once during part 3, each character can use the benefit granted by each ally:
Chwingas Charms. The character can reroll one ability check, attack roll, or saving throw, but must use the result of the roll.
Fluid Movement. The character can move up to their speed without provoking opportunity attacks.
Totemic Rage. The character has resistance against bludgeoning, piercing, or slashing damage from one melee or ranged weapon attack.
Hunter’s Salvo. The character can call in a salvo from a group of goliath archers, targeting a point that they can see within 60 feet. Each creature within 5 feet of that point must succeed on a DC 13 Dexterity saving throw or take 7 (2d6) piercing damage.
