Excelsior

Strange thing happened to me twice in Blighted Grove.
Once i was running from lady Mel through Drevo to the portal to waiting area. I was watching my hps so Abcesses wouldn't kill me, and all the way to the portal my hps were full. Suddenly after entering the portal I made a few steps in waiting area and died, with corpse remaining in waiting area. Another time I entered dungeon, ran to portal with full hps all the way, but in waiting area my hps got to about 40%. These death and hit are strange as even if i did miss 1 hit at the end it should've be ok for 230hp 195 dex autohealing, and I'm sure I had full hps when i entered portal still. I didn't seem to have any lag.
I suspect that some fireball was fired to me while i was running and hit me somehow after I entered the portal, making much more damage then it should be, which is wrong.

I think its the special from the Abscess

Iltar, getting hit without u notice it is possible, but i think u mistook the animation. Probably was not a fireball, but "breath attack" which looks exactly as a fireball. "Breath attack" usually deals a lot more dmg than fireball, cos it's based on monsters HP, not spelldmg/evaluate int. Also UO have spells with delay effect like explosion. If an explosion were casted on u and while u run a fireball casted as well, it is possible u were hit with both at the same time, making the fireball looks extremely powerful. Nothing wrong. It's how the game works.

The abcesses do have a nasty breath weapon that does a lot of damage. I have had the exact same thing happen. when they use it on you it is a guarantee hit, but I have noticed as long as you outrun the fireball, the damage is delayed, but once it hits... done.

Didn't realize that abcesses have firebreath. Thats because i play easy mode with pets and never died from firebreath there except that cases.
