The Navel is a level 34-36 Trial. It requires a light party of 4 players. In The Navel, players will face the mighty Primal Titan.
Strategy
There are a few mechanics to this fight that you should be aware of when beginning it. First, randomly throughout the fight, Titan will jump in the air and leave the battlefield, only to return a few seconds later and do massive AoE damage. The red circle will take up the entire battle field, and it seems the damage can be avoided by jumping at the correct time, going to the edge to avoid the circle will likely result in you falling off the level to your death. Titan has a knockback that he will randomly use on your non-tank members of the party. There is a nice sized windup time for dodging, but be sure to dodge as being hit will push you off the battlefield for an instant death. Last is his rock tomb, similar to the bubble mechanic from Hellbender in Brayflox's Longstop, though the tomb will not allow the CC'd person to cast spells unlike the bubble, so it's best to clear this quickly.
The fight is a rather straightforward tank and spank, around 50% Titan will jump in the air, but come back down quickly, and his heart will be revealed. Kill that and you win the fight.
