Weaknesses
Fire

Sui-Ki is weak towards Fire, exploit this weakness to secure more turns for your party.

Strengths

Attacks	Ice, Phys
Absorb	Ice
Void	Light, Dark, Ailments
Resist	Phys, Elec Force
Support	Focus, Beast Eye

Sui-Ki utilizes both single-target and multi-target Ice and Phys attacks, so we recommend bringing along demons that can block these types of attacks to cut off Sui-Ki's turns.

Sui-Ki can absorb Ice, and void Light, Dark, and Ailment skills, so don't use these attacks as you'll only be wasting your turn. Likewise, Sui-Ki can resist Phys, Elec, and Force attacks, although it is not totally immune to these types of attacks so get comfortable having a go at using them.

Sui-Ki has two Support skills including Focus which buff its attacks, and Beast Eye which grants Sui-Ki two extra turns.

How to Beat Sui-Ki

Cut Off Sui-Ki's Turns After It Activates Beast Eye

You can successfully cut off Sui-Ki's turns by equipping either Miasma or Wadatsumi Magatama to block its Ice attacks. Likewise, summoning demons that can block Ice attacks is also effective.

Not Totally Immune to Phys Attacks

Although Sui-Ki can resist Phys, it is not totally immune to this type of attack. Don't hesitate to use Phys attacks as it can still be effective in dealing damage.

Don't Use Light, Dark, and Ailment Skills

Sui-Ki can void Light, Dark, and Ailment Skills, so never use these types of attacks on it as you'll only be wasting your turn. While Sui-Ki can resist Elec and Force, it is not totally immune to these types of attacks, feel free to use them along with other elemental attacks, especially Fire as Sui-Ki is weak towards it.

Buff Your Attacks

Use a buff like Focus or Tarukaja before using a Phys attack. This allows you to maximize your Phys Attack's damage output in the short turns you get.

Use a buff like Makakaja before using a Magic skill. This allows you to maximize your Magic Attack's damage output in the short turns you get.

Debuff Sui-Ki

Use Tarunda or War Cry to lower its Phys/Magic Attacks. You will take less damage if you debuff its attacks. Use Rakunda to lower Sui-Ki’s defense, to make it more vulnerable to your attacks.

Alternatively, you can use Fog Breath or Sukunda as these debuffs will decrease Sui-Ki's chance of dodging your attacks.

Use a Magic Mirror or Makarakarn to Repel Sui-Ki's Ice Attacks

Sui-Ki utilizes Ice, and in the event you or your demons cannot block Ice, we highly recommend using a Magic Mirror or activating Makarakarn to repel its Ice attacks to cut off its turns and not take any damage.

You may obtain a Magic Mirror in Rag's Jewelry.

Use an Attack Mirror or Tetrakarn to Repel Sui-Ki's Phys Attacks

Sui-Ki utilizes Phys attacks, and in the event you or your demons cannot block Phys, we highly recommend using an Attack Mirror or activating Tetrakarn to Repel Sui-Ki's Phys attacks to cut off its turns and, at the same time, reflecting the damage onto it.

You may obtain an Attack Mirror in Rag's Jewelry.

Have At Least One Dedicated Healer in Your Party

Summon demons that have Dia or Media or other variations of the skill, so your party can restore HP as you move along the battle. This will be ideal especially in situations wherein you have no available Recovery items on hand.
