Combat Strategies

Element Stones

If you fail to destroy all five Element Stones within the time limit, Akumu deals heavy damage.

Flanking

Attacking Akumu from the rear deals significantly greater damage.

Unity

Every time a player dies, Akumu grows stronger.

Mode rules

The boss spawns immortal: whenever its HP drops to 1, it revives and levels up (see the level ladder). The HP removed within the time limit is converted into points.

3 attempts per week, reset on Mondays at 08:00 (UTC+1) — in a party of 1 to 5 members of the same Knighthood.

Akumu Mechanics

Facts drawn from the client tables and mechanics confirmed in combat. Values missing from the client are explicitly marked as pending.

Client data

Power gained from a KO+100% ATK

When one of Akumu's attacks defeats a player-controlled hero, the buff immediately applies 5 stacks.

Attack per stack: +20% ATKStacks applied / cap: 5 stacks1 hero defeated: +100% ATK

Rear-attack pressure+1%

Attacks from behind trigger an effect that increases Akumu's damage taken by 1% per stack.

Damage taken / stack: +1%Stack duration: 5 sStack cap: 100

The theoretical cap reaches +100% damage taken. Repeated rear hits build and maintain this short window.

Element Crystal Phase5 · 30 s

Akumu summons five Crystals. Destroy all of them before the timer expires or he unleashes a heavy attack.

Fire

Ice

Thunder

Wind

Earth

Outside Burst, each crystal has near-total resistance to elements other than its own. Once any elemental Burst is active — even a different element — the crystal becomes vulnerable and can be destroyed with any element.

Success: 5/5 destroyed15 s

The break chain opens a 15-second damage window.

ATK+25%

Damage taken by Akumu+50%

Failure: timer expires30 s

Akumu unleashes his heavy attack, knocks down heroes hit and applies this penalty for 30 seconds.

Critical damage-100%

Server data missing

Spawn trigger: The client sequence confirms the summon, but not the HP threshold or battle timing that triggers it.

Live combat HP: The client table contains an unscaled 10,000 HP base. It clearly does not match live combat HP; the server-injected value still needs to be measured.
