Patch Available - JMS 3.10

Polantaris and I tried going through the bosses with a lowbie today... We got all cleared except Vellum, and we either run out of time or Polantaris runs out of lives before we can beat him. We need at least another player, but no one is ever logged in anymore. Shit sucks.

It doesn't help that none of his hitboxes are appropriate to the animation size. The yellow aura for unburrowing is too small, and his fireball can hit you pretty far outside of the animation. I'll probably get used to it eventually but we can't kill him anyway even if I never died, he has too much HP for 15 minutes and doesn't stop burrowing for the first 7 or 8. If he was attacking the entire fight we would be able to kill him.

if they can be revived through water means, remember there exist an item that has the chance to turn temp pets perm

This item doesnt exist. The item you are thinking of will only allow you skip the pet quest for reviving a pet, not make it perm.

In JMS they occasionally add to the Cash shop an item that permanently revives your pet. My Fox pet can never die because of it.
