It is Bite of the Shissar. http://everquest.allakhazam.com/db/item.html?item=8511
(level appropriate for the rogue)
But it is summoned 3 at a time and of course it's free. Soooo it's good. When ROF came out, I still had over 100 in my inventory of the lvl 95 poisons, but when I got to 100, I am now summoning the new lvl 100 poisons, so tossing the old ones. Get it if you can. It's well worth it.
