This boss fight is annoying as hell man, so many attack chains and his staff's AOE spin attacks are just stupid ffs
Can anyone guide me or give me pointers on how to beat him?
You should be able to dodge without much trouble until the final phase. If you're struggling in the middle phase, you could try using a cloud step to help.
As soon as he starts spinning around the trident, activate Wind Tamer.
He should say something to indicate hes using the divine winds, and that’s your signal to use Wind Tamer.
This will stun him long enough for you to land a fully charged smash stance heavy attack
When his health drops to about a quarter, that's when he'll summon the tornado. As soon as he reaches that point, activate your transformation—Red Tides works best.
Stoneskin is super effective. He has a few moves that always end with a kick, and casting the spell during that kick will knock him over completely.
Also if you hit him while he's getting up from being knocked down with any move that staggers, you can easily send him back to the ground.
You can chain this together: Stoneskin → topple → Spirit Attack → topple → focus move → topple.
The camera always zooms out before he does the throw move, and it has a long wind-up.
