I just ran Underbog time walking dungeon. My group had just killed Ghaz’ran as he walked up the ramp from his pool. I was half way up and just looted the body, and I went to get a quick drink. I was gone go no more than 20 second and came back to a corpse. I checked the combat log and the frenzy fish killed me, OUT of the water, 1/2 way up the ramp! I never went INTO the water until the jump past the following platform!
If you aggro the fish before Ghazan is killed, they will kill your character even if it is on the walkway where the mobs were. Those fish are mean.
I never went in the water until AFTER that boss. I only went 1/2 way down the ramp.
The fish can kill someone if they aggro on them even on the walkway up above.
Once a frenzy aggros on you, the only way to stop it is to kill that fish. It will remain aggro’d on you after the boss is dead.
