This all happened in the space of 30 minutes:
1. My low level character is set upon by a stealthed leopard. Low and behold I am wounded and near death as i try in vain to kill it with my bow. But wait there's more I try my two hotkeyed heal kits - nothing happens. I try and drink a ptn - nothing happens. I only survive by the grace of a killing bow. WTF? No Lag to speak of nothing else on the screen except it and me.
2. I buff up on one screen and then am de-buffed on the next.
3. Up against a gorgon it casts Ghostly Visage, Bull Str and Barkskin as it proceeds to crit me for 40hp!
What is going on? Either a DM/Quasi-DM or sadistic grunt was on having fun at my expense or I was imagining the whole thing but alas I was not because I was partied with one other person and we both suffered similar misfortune.
So please if this was DM intervention - please go away. Because the particular DM(s) in question's "assistance" is not appreciated.
Oh just for the record I have been on this server nigh on 2 years so am no newb. This stuff is no *bug*!
Happy hunting

And yes shame on you. You know who you are.
