Necrophage will increase its maximum HP by 15 points (if killing a character) or 5 points (if killing a pet) to a cap of 210 HP. -- https://wiki.nexusclash.com/wiki/Necrophage

I tried to nurse my baby Necrophage with some yummy pets so that the poor thing wouldn't get killed so easily, but after killing 5 tentacles and returning home, I am sad to see that the Necrophage still has just the 60 HP it started with.

- Your pet Dead Inside, a Necrophage, attacked Horrid Tentacle and hit for 13 points of slashing damage. You gain 6 experience points! This was enough to kill them! You gain an additional 12 experience points! (2022-03-12 19:27:11).

Further animal studies were done, max HP 90 before a pet kill and 90 after the kill.

I recruited another pet master and we sacrificed their pet in the darkest corner of Stygia.

- Your pet Dead Inside, a Necrophage, attacked Possessed Bloody Ice Chunk and hit for 15 points of slashing damage. You gain 7 experience points! This was enough to kill them! You gain an additional 14 experience points! (2022-03-13 16:49:51).

I was first thinking that maybe the max HP gain was nerfed against wandering pets, after all, killing Imps would be easy way to make Necrophage gain HP and that Tentacles would get counted as wandering pets too. But seems like this is not the case.

There's a pending fix for this.
