Making an all / all cloak w/ the minion of discord focus on it..... Would require soe to have coding and files for that effect for EVERY PET IN THE GAME. It would do weird things for an enchanter pet if the files were not present. Most likely issue would be that every time an enchanter who was wearing this cloak cast a pet, said enchanter would crash to desktop if those files were not present. Its one of the reasons why they disabled the coadjutor mechanotablet. The resulting aug was all / all. Sigh, I wish that said aug still worked.
Its annoying, cause its a NICE cloak. But, then, the pet focus range offa bert in timeb is a nice range item, in and of itself.
I honestly don't know why they don't put the pet Foci augs back in the game. With the advent of TSS, items with pet Foci became available to more than just the NEC/BST/MAG cliques.
All pet classes. I think there is another pet type effect missing. Something about surrounding your pet in darkness if I remember correctly about the link I saw in /gu.
