Oceania Master

Technique

This boss can be tricky for 2 reasons:

1. He spawns hands which need to be killed ASAP. They have 10 hp so can be killed in one hit. If any are left to explode, it can result in a squad wipe. Squads will commonly designate one person to deal with these (an archer/BM with bow) while the rest of the group concentrate on killing the boss.
2. He spawns a "mini-me". Do not hit this monster under any circumstance. Do not use AoEs. Do not tab onto him by mistake. Just don't hit him. If left to his own devices, he will soon get bored and die anyway. He won't do damage to anyone so you don't need to worry about it.

Other than the above points, the boss is very straight forward to kill. It is herc tankable, though people commonly prefer the barb to tank this guy.
