Billy, the Greatest Bar Guest

Shapeshifting. The bar guest can use his action to polymorph into a goblin or back into his true form. Other than its speed and size (Small), his statistics are the same in each form.

Keen Smell. The bar guest has advantage on Wisdom (Perception) checks that rely on smell

Banished by Flame. When the bar guest starts his turn in a source of flame that engulfs him, he must succeed on a DC 15 Charisma saving throw or be banished to Mabar. Bursts of flame such as a fireball or dragon’s breath do not have this effect.

Spellcasting. The Bar Guest has innate spellcasting. His spellcasting ability is Charisma (spell save DC 14, +5 to hit with spell attacks). The Bar Guest has the following spells innately prepared requiring no material components:

At will: [levitate] , [minor illusion] , [pass without trace]

3/day each: [charm person], [dimension door], [suggestion]

Billy's precious: While wearing this ring, Billy can take a Magic action to give himself the Invisible condition. He remains Invisible until the ring is removed or until he takes a Bonus Action to become visible again.
