Aciel Pre-Battle Guide

Strengths and Weaknesses

Weaknesses

Aciel does not have any elemental weakness, however, using both but Phys and Magic attacks is useful for dealing damage.

Strengths

Aciel utilizes Almighty attacks including Mana Drain and Sol Niger, a multi-target attack that reduces foes' HP to 1. Likewise, it also uses Phys attacks, so we highly recommend to always use an Attack Mirror or Tetrakarn to avoid situations where all it takes for Aciel to kill you is by attacking after it drops your HP to 1.

Aciel can reflect Dark and absorb Light and Ailment skills, so never use these types of attacks as you'll only be wasting your turn. It also has three Support skills including Dekaja, Dekunda, and Dragon Eye which grants Aciel four extra turns.

How to Beat Aciel

Always Dedicate a Turn to Use an Attack Mirror or Tetrakarn Against Sol Niger

Aciel uses Sol Niger, a multi-target attack that reduces foes' HP to 1. Likewise, it also uses Phys attacks, so we highly recommend to always use an Attack Mirror or Tetrakarn to avoid situations where all it takes for Aciel to kill you is by attacking after it drops your HP to 1.

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

Buff Your Attacks But Don't Overinvest

Aciel has Dekaja which negates all your party's buffs. It is fine to still buff yourself and your allies but don't overdo it or Aciel will simply cancel it out in a single turn.

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.

Don't Overinvest in Debuffing

Aciel has Dekunda which negates your Debuffs on it. It is fine to debuff Aciel but you shouldn't overinvest or Aciel will simply cancel it all out in a single turn.

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 its defense, to make it more vulnerable to your attacks.

Alternatively, you can use Fog Breath or Sukunda as these debuffs will decrease its chance of dodging your attacks.

No Resistance Against Phys Attacks

Aciel has no resistance against Phys Attacks, so don't hesitate to use these types of attacks on it.

No Resistance Against Magic Attacks Except for Light, Dark, and Ailments

Aciel reflects Dark, and absorbs Light and Ailments. However, be comfortable using other elemental Magic attacks as Aciel cannot block or counter these.

Have At Least One Dedicated Healer in Your Party

Summon demons that have Dia, Media, or the skill's other variants, 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.
