One build
Fire giant - cloud giant - storm giant
Sword
Trapping/cry - for more utility take landslide and drive mobs around to control the battle. (sometimes there are 2 boss type mobs and driving one off can make things easier) I've used it a ton in PvE.
Tank with heavy swords and use cry after the tick to maximize damage and healing
For second spec take either polearm for more tanking options or axe to disembowel high hp mobs since the time between writhing and convulsing can be many rounds.
Another build
SUPER EVASION
wood-elf - high elf - dark-elf
sword/fist
flow/fluid
Use evasion for counterpunch and tank like a god while doing blunt damage
or
wield swords, tank like a god hit vulns and evade everything while you spam feint for incredible mob dps negating.
