This spell doesnt work at all. see picture for error message.
The lower level version called Rage of Zomm works like an enchanter pet in that it only attacks once you get hit but its damage output is a lot higher and life less than a normal pet. (these pets on eqlive are actually temp swarm pets but swarm pets dont work on emu servers so the code was messed with).
Only way i know to get the spell fixed is to copy the rage of zomm code but up the pets level to 70 instead of 55 and adjust its stats up a lot to match the upgrade.
All mage swarm pet aas are broken like this also so if you wanted you could go into that code also and customize it to make the swarm aas summon custom perm pets also.
