Tidewalker Depth-Seers can be found in Serpentshrine Cavern.
- These drop a hefty HoT on things which needs to be dispelled.
- At lower health they'll chaincast an uninterruptible tranquility that people need to DPS through.
- Because of the uninterruptible healing, its prudent to kill them after you've killed all the other non-CCable murlocs so you don't waste too much time until you have your full raid able to focus fire on them
- They don't seem to be vulnerable to polymorph, snares, stuns and fear.
- They are vulnerable to spell interrupts, but immune to silence.
- Melees on plate for ~1500-2k
