Hunters/Rangers: It's best to actually get a Handgun and stay away from it, especially in Ultimate when its projectile can kill in one hit. Both Hunters and Rangers might want to try a Mechgun and time the attacks to keep the Mericarol stunned in place.

Forces: Mericarol is weak to Barta. Just stay at a distance and fire Barta. It's actually going to go like this: Cast Barta, evade attack, Barta, evade, Barta, evade, ad nausem.

Leader of Gee enemies.

Hunters/Rangers: The Gi Gue is unpredictable, but it's going to keep itself invulnerable for most of the fight. Try to get close while being away from its front at the same time. When it is vulnerable, unload with everything you got. Be careful: a continuous string will cause it to exude its spike bomb, or Jellen and Zalure.

Forces: The Gi Gue doesn't like Barta, so that invulnerability shield it keeps up the whole time will keep you on guard. Don't forget that there's a bunch of those poison blobs around to throw off your aim, and there's no shortage of Gees around the Gi Gue. Try to keep at least one Gee alive so you won't have to deal with four.

Leader of Ul Gibbon/Zol Gibbon enemies.

Hunters/Rangers: Definitely cast anything to increase your Defenses or decrease attack power of enemies, because Gibbles is very angry, but very open. Wait till it's close enough so it tries to hit you, and then hit it from the sides. RUN when you see it leap high, and repeat when you're given that grace period when it tries to recover from its landing.

Forces: Same deal as above, while dealing Barta. Cast Deband and Jellen.
