Side Quest: Supreme Rice Omelet (Q-16)
Recommend Level: 39
Teleport to "Ancient Mountain Path - Abandoned Clifftop Huts", then proceed to the next area (C).

Preparation
This boss is tough because it requires Zinikr, and he is low in level, you can farm level a little bit but not necessary.
- I assume that your Zinikr is at least level 34: you need to unlock the follow skills "Safe Taunt", "Taunt Turns+", and "Jewel+". You SP should be just enough for these.
- If Leo has any "Counter" or "Support & Fight" skills, remove all of them.
- Equip Amethyst M and Emerald M on Zinikr. Then highest weapons and armors for everyone else.
Walk toward the center for the battle.
Strategy:
- IMPORTANT: Do not allow it to "Charge" 4 times, or it's game over. That's why Zinikr must use "Taunt" every time when it's his turn (there is a chance that you can miss Taunt).
- I suggest you kill only 2 minions in front of Leo so that you can use "Samidare (Fire+1)". If you kill more than 2, it'll summon them back to a total of 6.
- Ez keeps buffing your team with "Quick All" and heal with "All Potion L v2". You may want Leo to help heal Zinikr as well when he is low.
- When Leo has free turns, use "Concentrate" + "Samidare (Fire+1)" for damage.
- As long as you keep Zinikr alive, you shouldn't have any problem in this battle.
Teleport to "West Vence - Marketplace" and walk toward the market for a small scene. Then make your way to the bar and talk to Cas for rewards.

Rewards:
- (I-07) Amethyst L
- (I-08) SP Capsule
