KOF: Britannia
Determine the best fighters in Britannia! This event follows a tournament format where you select 1 team out of multiple to begin the tournament’s Round of 16 in an arcade-style battle.


Use Fighter Coins to start the battle. Since all three heroes on the team must be set to participate, Fighter Coins can also be used to hire supporting heroes if you do not have one (only in Normal and Hard Difficulties).
Note: You can get a lot of Fighter Coins from Boss Battles and Death Matches. Get more rewards by winning the tournament with various pre-selected teams on all difficulties. Challengers will abruptly appear as you progress through the tournament. Defeat them to get rewarded with Awakening Stones and Tokens of the Fighter King.
Difficulty | Recommended CC | Condition | Note |
Normal | 40,000 | Equipment Stats Not Applied | Suitable for players who are playing The Seven Deadly Sins: Grand Cross for the first time. |
Hard | 67,000 | Equipment Stats Not Applied | Suitable for players who have cleared Chapter 7 or higher. |
Extreme | 120,000 | Equipment Stats Applied | Suitable for players who have cleared Chapter 12 or higher. |
Losing in battle means GAME OVER, and you must start from the beginning. Fighter coins can be used in Normal and Hard difficulties to continue the battle. You can also use the restart button to start from the beginning in case the difficulty is too high or if you’d like to use a different team.
Event Exchange Shop
Use the tokens acquired from KOF: Britannia tournament to exchange for Special, Growth, and Costume items!
Ultimate Final Boss Omega Rugal
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!
Strategy
- 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.
- 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.
- 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.
