Celestial Sugarglider

Traits

Celestial Bond. The sugarglider’s hit points increase by an amount equal to the druid’s proficiency bonus. If it dies, it dissolves into motes of starlight, reforming at dawn when the druid completes a long rest.

Flyby. The sugarglider doesn’t provoke opportunity attacks when it flies out of an enemy’s reach.

Channel Star Magic. When serving as a familiar, the sugarglider can deliver any spell with a range of touch that the druid casts, as though the druid had cast it from the sugarglider’s space.

Radiant Nibble. Melee Weapon Attack: +5 to hit, reach 5 ft., one target.

Hit: 5 (1d4 + 2) radiant damage.

 Luminous Dust (Recharge 5–6). The sugarglider exhales a cone of shimmering celestial dust in a 15-foot cone. Each creature in the cone must succeed on a DC 14 Dexterity saving throw or become outlined in starlight for 1 minute.

While outlined, a creature sheds dim light in a 10-foot radius, cannot benefit from invisibility, and attack rolls against it have advantage if the attacker can see it.
