Angulotl Yegg

Retainer. The retainer has the same level and proficiency bonus as its mentor. It has proficiency in Acrobatics, Athletics, Stealth and Survival checks, as well as in all saving throws.
It also has a number of hit points equal to 7 times their level, as well as a number of d8 hit dice equal to its level.

7th level: Multiattack. The yegg makes two Poison Knife attacks.

Signature Attack (Poison Knife). Melee or Ranged Weapon Attack: +3 plus PB to hit, reach 5 ft. or range 20/60ft., one target. Hit: 1d4 plus PB piercing damage plus 2d6 poison damage.

7th Level: Excoriating Acid (3/Day). As an action, the yegg throws a flask of acid at a point they can see within 20 feet of them. The flask shatters, and each creature within 10 feet of that point must make a DC 10 plus PB Dexterity saving throw, taking PBd10 acid damage on a failed save, or half as much damage on a successful one.

3rd Level: Death from Above! (3/Day). As a bonus action, the yegg jumps up to their walking speed without provoking opportunity attacks. If they leap over an enemy during this jump, the yegg can make a signature attack with advantage against that enemy. On a hit, this attack deals an extra PB piercing damage.

5th Level: Lay Low (3/Day). When the yegg hits a creature with a signature attack while hidden, the yegg can use their reaction to remain hidden.
