World Boss is a weekly battle mode found under 'Battle' in Grand Chase Dimensional Chaser.
In World Boss you fight against Harkion with 3 different parties for each phase. In each phase Harkion's attacks are different and there's a different debuff.
There is no HP limit to Harkion, and he cannot be killed. The idea is to deal damage as much as possible. The higher the damage is, the better are the rewards.
Every 10 seconds, a icon appears on the left, stating that Harkion permanently become stronger every 10 seconds, and stacks up to 17.
Phases
World Boss has three phases:
Phase 1
"Magical Damage Reduced by 50%"
In the first phase, Harkion will directly attack the party, alternating between charge claw attacks and laser beams.
Phase 2
"No Damage Reduction"
In the second phase, Harkion will zoom around, casting explosions. After doing this three times, Harkion will fly into the center of the map, splitting into four clones and leaving behind a crystal that can be picked up to boost attack speed. The clones cannot take critical damage. Harkion will enter his clone phase twice per battle.
Phase 3
"Physical Damage Reduced by 50%"
In the third phase, Harkion barely moves, casting mortar attacks on the party as well as roaring shock waves. At set intervals, he will also summon monsters that give SP when destroyed.
