Brush Buddy

Absorb Ink. Due to Brush Buddies natural attraction to ink and other liquids with magical reagents, they have the ability to soak up an amount of liquids into their hide. As a bonus action, a Brush Buddy can absorb an amount of liquid equal to a 5x5 ft square. If the liquid has any dangerous components, such as acid, the brush buddy is immune to an amount of damage equal to half of it's total hit point score (6). The brush buddy can spend a bonus action to release any liquid it absorbs into its hide. The liquid absorbed by the Brush Buddy can be held for a single day, at which point the Brush Buddy either releases the liquid or absorbs it entirely. 

Tail. Melee Attack: +0 to hit, reach 5ft., 1 target. Hit: 1 (1d1) bludgeoning damage, and if the Brush Buddy has any absorbed liquid with damage or saving throw related properties, the target takes 1d4 of the damage associated with the liquid, as well as having to make a saving throw against the liquids condition effects (if any) at a lowered DC of the same save type (DC 13).
