Ultimate Final Boss Omega Rugal

KOF Final Boss Rugal.jpg

The Ultimate Final Boss Rugal Event is one of the 4 playable contents for the 7DS x KOF’98 collaboration event. It can be unlocked after clearing [Revival of Evil] World Quest. This event is played like any other Final Boss fights and we will highlight some of the best heroes and team composition against the Ultimate Boss from KOF’98.

Participants can gain Final Boss Omega Rugal Points as a reward that can be exchanged for growth support items and limited-time KOF’98 hero costumes in the Final Boss Exchange Shop. A huge amount of stamina is needed to enter the Final Boss battle that may require you to spend some of your Stamina Recovery Potions.

The event runs in a span of 2 weeks from 10/26 - until 11/9.

Note: Placing in the top 30% will give you a Combat Gloves costume for Omega Rugal, so do your best to shoot for a high score!


  • Use heroes with Ignite skill as the damage is increased by 15% for each Ignite effect on Omega Rugal.
  • Do not use heroes that rely on Buff skills as the boss can change the situation to his favor. Omega Rugal reduces damage taken by 50% for each buff. Moreover, he removes buff effects when attacking an enemy and inflicts 30% more damage per buff removed.
  • Use HP food and equip Life set on your Support Heroes. Only damage dealers should be equipped with an Onslaught set. The reason is that you’ll end up with more points in proportion to the Combat Class and the remaining HP of your team.
  • The strategy in Phase 1 is to prolong the battle until all your heroes’ ultimate move gauges are full. Just use skills or move cards as you stack ignite effects and continuously dissolve Omega Rugal’s ult gauge. Chip-in some damage and lower the boss’ HP but do not totally deplete his HP bar until the conditions are met.
Turn 3
  • When your heroes’ ultimate move gauge is full (ideally at turn 4 or 5), you can now use skills (excluding ultimate) to kill the boss and enter Phase 2.
Turn 5
  • Now with all your ultimates ready, Phase 2 should be finished in about 1 or 2 turns. Keep in mind that Omega Rugal recovers his HP back to full if he survives with 10% HP or less, so make sure that the last hit should be a significant blow, or else you’ll most likely lose the battle. You’d also not want to prolong Phase 2 because starting from turn 3, the boss will heal 30% of diminished HP every turn.
Turn 6
Turn 7
