He changes weaknesses depending on the phase:

During his first phase, he is weak to all Magic if the flames are spent, when instead the sparks and flames spark he is neutral and resistant to all non-fire attacks, respectively.
So what you want is to focus on the first one with magic attacks.
You can actually absorb him in the first turn with this combo:

1. Parry everything but the last attack
   
2. Guard Counter the last attack
   
3. Teleport
   
4. Perfect four-hit combo, breaking the block
   
5. Ice Lv 2 + Assist
   
6. Lightning Lv 2
   
7. [Instant Switch]Wind Lv 2 + Assist
   
8. Seal full combo+chain
   
9. Bow Technique
   
10. Absorb

And that's why Instant Switch is the most important Union Skill. Bow Technique is actually overkill with full upgrades, so you should at least have him set up for the next turn

During his second phase he is weak to Neutral Magic so your priorities should be :

• Seal Technique
  
• Whip Technique
  
• Seal Combo
  
• Deflect
  
• Counterspell

Seals in general are useful as they deal no health damage(and neither does Deflect), and the Seal Special allows you to set-up great two-turn combos, especially since you don't want to stale Bow and Whip Specials

Speaking of which, one of the worst mistakes many make is to stale your moves. From the second time in a turn they'll deal half absorb damage and get worse with more stacks, while only removing one stack per turn. Deflect and Counterspell obviously aren't affected by staling

The third phase has no weaknesses, but the Whip Combo, Lightning Lv3 will hit both the first arm and the main body(or the main body and the rear arm if the first arm is destroyed), while Unified Division and non-charged Bow attacks will hit all three, not that the latter is much use

If you still get him killed, feed him lv 3 Fire which he'll absorb(except for the first phase if the ground isn't ablaze). You should never need to, however.
