Ose Pre-Battle Guide

Strengths and Weaknesses

Weaknesses

Ose has no elemental weakness, however using Phys attacks on it and Magic attacks except for Light, Dark, Ailment, Mind, Curse, and Nerve skills are effective in dealing damage.

Strengths

Ose uses a multi-target Phys skill, so we advise raising the party's defense whenever you can. Ose can also Void Light, Dark, and Ailments, so never use these attacks at any point.

Likewise, Ose can Resist Mind, Curse, and Nerve, we suggest using these skills at a minimum.

Ose also has a multitude of Support skills. Be extra careful whenever he uses either Tetrakarn or Makarakarn as the damage you afflict him with will repel back to you.

How to Beat Ose

Be Cautious When Ose Activates Tetrakarn or Makarakarn

Be extra careful whenever he uses either Tetrakarn or Makarakarn as the damage you afflict him with will repel back to you.

Don't Overinvest in Buffing Allies

You can still buff your party however, take note that Ose has Dekaja which can cancel out all your buffs 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 Debuffs

Ose can activate Dekunda which will remove all debuffs you use on it. You can still use debuffs but be cautious!

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 Ose’s chance of dodging your attacks.

No Resistance Against Phys Attacks

Ose 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, Ailments, Mind, Curse, and Nerve

Ose Voids Light, Dark, and Ailments skills, and can Resist Mind, Curse, Nerve. However, be comfortable using other elemental Magic attacks as Ose cannot block or counter these.

Have At Least One Dedicated Healer in Your Party

Summon demons that have Dia or Media 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.
