Side Quest: Omega (Q-20)
Recommended Level: 50
Thaumatech Factory - Rooftop
Teleport to "Thaumatech Factory -> Rooftop", then walk pass the elevator.

Thaumatech Factory - Depths
This level is like a puzzle that you have to solve. Basically, you have to find and activate all container cranes.
There are 3 areas, and you'll have to go back forth between them. I'll just show the image step by step below. Follow the number from (1) to (17). If you see 2 numbers in the same spot, which mean that you have to come back later.


- (I-01) Pearl XL: Machine Chest Bottom-left.
- (I-02) Onyx XL: Machine Chest Top-left.
- (I-03) Diamond XL: Machine Chest Bottom-right.
- (I-04) SP Capsule x2: Machine Chest Right.
- (I-05) Opal XL: Machine Chest Top-right.
At this point, you should have collected all Machine Chest. Now save the game and prepare for battle.
Before proceed, make sure that you are at least level 50.
Preparation
- Recommended Party: Leo, Prickle, Ez.
- Bring all your Lightning skills.
- Unlock Prickle's Tension skills Tempest, Tempest+, and Tempest & Quick.
- Equip Diamond XL and Diamond L on everyone.
Strategy:
- Omega has 2 energy tanks powering its arms and the damage each arm deals to you is based on the energy provided by the energy tanks.
- Each tank has 15000HP. Your priority is to lower energy outputs of both energy tanks (you cannot destroy them because whenever the boss use "Overboost" skill the energy tanks will be reset).
- Its right arm (your left) is more powerful than the left arm. So you should focus on attacking energy tank on your left. My suggestion is to destroy left energy tank then bring the right energy tank to yellow, so that you have free turns to attack the body.
- Always maintain "Quick All", "Attack Up All", and keep your health above 90%.
- When the boss uses "Overboost" (when the countdown reaches 0), both energy tanks will reset, so you'll have to quickly destroy both of them. Use Prickle's Tension skill "Tempest" if you have (it deals around 14000HP), then use Ez's "Shock Grenade" to finished them off while Leo attacking its body. If Tension skill is not available, have Leo helps to destroy the tanks.
- Notable additional skills:
- Using "Mega Barrier" can drastically reduce the damage from "Overboost" giving you 100% chance of survival. Just try to cast it before the countdown reaches 0.
- Ez's "Bounce" skill can be helpful in amplifying "Plasma" allowing to quickly destroy energy tanks and deal damage to the boss.
- Prickle's "Support & Charge" is also useful.
- Repeat until you win.
Reward:
- (I-06) Positron Blaster
