That was painful. Never did SSC so when I saw a big pit I thought it was like one of the WOTLK instances we recently did and jumped... eheh. Had only caught the whole "jump into the water make sure you don't take fall damage" <_< Died again to fish at the right place as I didn't know they saw stealth... Eventually decided to skip jumping in water and just stealth past things, though armor was off this time, got to pipe, jumped in, franticlyescaped fish.
Fish, get acheivement. Though, I shadowmelded right after (before he appeared) as I intended to HS out but instead he saw through it and white hit me unstealthing me and killed me. Not sure if I was unlucky or if it was changed, I wasn't standing particularly close.
Soo lessons, don't jump down shafts, it might be an elevator... This brings back memories of a similar mistake with Half Life <_<
Don't bother with the water walking if you can stealth and are 80. :P
