I was doing a team mission tonight and looted a "Ring of Power - Physics" QL 19 which had a very distinguished description and a fairly decent looking result: +3 chem, rad, and (something else) damage ADDED when worn.
I put it on and it did absolutely nothing... at least from the damage logs. I petitioned a guide and since I was a guide for 6 months in EQ I know when I'm getting the run-around (ie: wait around 15 minutes while a newbie guide asks all the senior guides in guide channel): he had no clue what the item was or what it was supposed to do. His final verdict: "you are level 21 and it is QL 19 so it doesn't work". Couldn't help from laughing.
Seems +9 damage add is pretty crazy for QL 19 but considering it is "legendary" and for "omni seniors" I think it's gotta be a bug?
