Get ready to dodge sideways when he roars and flames up never backwards cause the hitbox is huge. Watch for the ground pound and three-hit combo, those are your best chances to get in couple quick hits then back off. The pillars around the arena work great for blocking his flame breath, and if you got the Fireproof Mantle from Elder Jinchi itll help tons with the fire damage. Snake transformation lets you deal safe damage during his attacks, and you can use Immobilization spell to stop his big fire explosion buildup.

Good to know the patterns stay same even with flames just bigger reach so learn the basic moves first. Dont get greedy with attacks, just take your time and get in safe hits when you can cause rushing will get you killed fast. Tip if youre really struggling focus on just dodging his moves for a few attempts without attacking just to learn the timing, makes everything much easier once you got that down.
