105 Silver Mage. Air pet and healer merc.
When agroed, the Tidalmage warps to the bottom of the gangplank at -632, -576. Just like the PH does.
If you park pet or wait at this point then fight will be contained on the spot, otherwise you can end up warping underwater and going TU.
Mob is very resistant to fire and magic spells, probably other lines too, so I just concentrated on keeping pet DSed and chain casting swarm pets.
Quite a common pop too, I believe.
