Bolstering Battleaxe

Weapon, rare (requires attunement)

The wickedly curved blade of this weapon grants the wielder a +1 bonus on attack and damage rolls. In addition, anytime you damage a creature with an attack with the bolstering battleaxe, you gain a +1 bonus on saving throws against any abilities that creature uses against you before the beginning of your next turn. On a critical hit, you gain advantage on saving throws against that creature’s abilities rather than a +1 bonus.
