Rogash

Rogash is one of the leaders of Draakons. He appears only briefly in instance Inside Rogash's Sanctuary during Exodor questline. He also appears in Vogzu's cutscene when entering Free Exodor Base.

Rogash has his own manor on the first island of Exodor, the Rogash's Garden. Rogash is a technical mastermind who built the LB-1 walking tank.

Rogash is the last dungeon boss who finishes the Draakons-Exodor story arc. After loss of Lumikan he becomes mad and plugs himself directly into Black Core energy in Fusion Laboratory.

Mechanics
Fusion Laboratory is last of those single-boss dungeons that were released after Exodor based on player feedback. Mechanics of bosses are slightly more complicated that before.

Some attacks apply Weak Current debuff which has DoT and you explode on 3 stacks. Same happens if you get hit by Rogash' energy attacks which he shoots to his front and back. You explode, and take anyone nearby with you. You can actually survive the explosion if you can move away from it, or priest pulls you out.

Boss will apply stun check after several mechanics and uses his blade to grind you to pieces if you were stunned. "I will crush you." Healer or brooch can ofc cleanse the stun.

Laser Turrets
Panels of Core Energy are summoned at 80% of boss HP. They fire lasers on a player every 60 seconds after "Targeting or "Target analysis is compete". Target player is also indicated with an eye above their head. Damage is moderate, but anyone who gets hit might get stunned. This also includes players who are not laser target.

Donut wave
Starting from 80%, announced with "I'll show you what rage is!". Direction depends on color of the orb on his hand. (Blue in->out, red out->in). Wave knocks you down. There is second wave soon after first.

Shield phase
Shield phase is announced with "Kwaaah!". Boss runs to middle of arena. Break the shield within 10 seconds or a wave of energy wipes off everyone with "There will be nothing left of you!" (lancer can block this, also you can outheal it in solo version.) Repeats every 120 seconds.

Puddle AOE and mini waves
Announced with "Waaah!"

Three heavy damage puddles spawn in middle of room. Puddles stagger (use shields or Rallying Cry to walk out). Waves spread from side from drones. You must stand between the puddles to avoid damage. Hitting by wave is insta-kill, but can be iframed.

The power of Red Lightning
Lasers hit Rogash on middle, stunning him and everyone who gets hit by laser. Wave comes out of him when he recovers after 3 sec. Stun him again or get wiped by red energy waves.

Wave is announced with when boss says "Argh..." and usually run to the middle. "Core Energy charged". "This is the power of Red Lightning!" releases the wave.

Iframe over the wave from out to middle direction and hit boss with stun. You must position yourself so that lasers don't hit you. Normal mode has four lasers shooting at boss from four cardinal directions.
