Charm fade by invis

[Angelox]

Also pets poof when you invis , I remember building some AAs, so this wouldn't happen.

EDIT:Well, anyways, it was like that when I played - made you want to get those AA's

You're right, Angelox. That was the way it was early on, but sometime (around Luclin, I believe), there was a patch that made it so pets would not poof if you went invis. It was around the same time they changed the way NPCs viewed pets; indifferent unless they took an action, so a lost pet trying to find its master wouldn't bring a train.

I confirmed during the free time this summer on Live that casting any sort of invis spell on yourself will break the charm on any charmed pets you have.

yeha it was a real pain in the arse to be a pet class before that - you could not run throw a green dungeon wihout kiling every stupid green mob cause they would all agro on your pet

This code causes a zone crash when the player uses an invis spell and has no pet up. Here is the output:

void Mob::SetInvisible(bool state)

    invisible = state;
    SendAppearancePacket(AT_Invis, invisible);
    // Invis breaks charms

    if ((this->GetPetType() == petCharmed) && invisible)

Always make sure a pointer is valid before using it.
