Periodically she will cast a Geyser on a player, which shows as a blue patch on the floor. The does a nasty Shock Blast, which can and should be interrupted. In the back of the room an other trash mob, some merlocs running around and we are up to the first boss. Again is it preferred to cc as much of the casters as you can. At the end of the hall way up the stairs a big group of trash. Constantly there will be groups of merlocs spawning and running around. It is advisable to cc the casters/healers or at least get those down first. But I usually jump when the jelly fish lands, he did leave me behind on the bottom ones…. You can walk up on the elevator, before the jelly fish is down. This one is painfully slow, but only needs to be used ones. The hall ways left and right are closed of by big tentacles, so the only way is straight ahead.
Not too hard as long as everybody stays out of the green ‘fire’. At the top of the stairs is a kind trash boss. The trash in the first hallway is not difficult yet. It is a very beautiful underwater Dungeon and has 5 bosses on two levels. The other dungeon you can get into right from the start is Throne of the Tides.
