Nilbog Trickery

Goblin

You learn the mischievous ways of your spirit-possessed kin, able to taunt and fool your enemies with ease. You gain the following benefits:

• You learn the vicious mockery cantrip. If you do not have a spellcasting ability, treat Charisma as your spellcasting ability for this spell.
• When a creature you can see targets you with an attack or a harmful spell, you can use your reaction to force the creature to first make a Wisdom saving throw. The DC for this saving throw is equal to 8 + your proficiency bonus + your Charisma modifier. On a failed save, the creature must choose a new target or lose the attack or spell. This ability doesn’t protect you from area effects, such as the explosion of a fireball. Once you use this ability, you can't use it again until you finish a long rest.
