Mob Control: Kraken Clash Optimization Guide

What is Kraken Clash?

Kraken Clash is a 7-day clan event with two distinct phases. During days 1–6, your clan completes Clan Missions that make tickets available, but you must manually claim your tickets after each mission completes. Unclaimed tickets are lost. On day 7, the Kraken boss fight unlocks for a single day, and you spend your accumulated tickets to battle it. The event earns Sparks and event-specific rewards but does NOT earn Stars. It exists solely to drive Sparks generation, making it the single most important event for your monthly clan Sparks contribution and the event with the highest Sparks ceiling in the game.

The event uses a ticket-based entry system. Completing Clan Missions during phases 1–6 (days 1–6) makes tickets available, but you must manually cash in to claim them. Unclaimed tickets are lost; they do not auto-collect. Missions refresh on a timer, so completing and claiming daily is critical. On day 7, you spend all your accumulated tickets on the boss fight. Complete and claim every mission every day so you enter the fight with maximum tickets.

During days 1–6, "participation" means completing your Clan Missions and manually claiming your tickets every day to accumulate as many as possible. On day 7, it means spending all your tickets with an optimized loadout and fight timing. Completing and claiming missions every day during the ticket phase is just as important as playing well on fight day. A player who claims tickets all 6 days and fights optimally on day 7 will far outperform someone who skips half the mission days.

The Optimal Loadout

The key theme across all four picks is: against a single boss target, concentrated damage per unit and survivability outperform speed and swarm tactics.

Big Bertha (Cannon)

Big Bertha is the recommended cannon for Kraken. It fires fewer mobs than other cannons, but each individual mob hits dramatically harder than anything else in the game. Each Bertha mob functions almost like a giant with high individual HP and damage output.

Against a single boss target like the Kraken, concentrated damage-per-unit outperforms mob spam from faster-firing cannons. You need each mob that reaches the Kraken to hit as hard as possible.

The tradeoff: slower fire rate means higher risk if your mobs get killed before reaching the Kraken. The supporting units (Raccoon, Sirion, Summon Gate) are all chosen to complement Bertha's weakness by maximizing the chance that your high-value mobs survive long enough to deal their damage.

Do not use Triple Cannon or other speed-oriented cannons for Kraken. They produce lots of weak mobs that will die before dealing meaningful boss damage.

Raccoon (Mob)

Raccoon is the recommended mob type for Kraken. It multiplies fastest through gates and receives a unique speed boost when passing through multiplier gates. This helps Raccoon mobs actually reach the boss before dying, which complements Big Bertha's "fewer mobs but each one counts" philosophy.

If your Raccoon is significantly under-leveled, Alien is the backup pick, but prioritize getting Raccoon leveled for the long term.

Sirion (Champion)

Sirion is best-in-slot for Kraken. Its ranged attacks allow consistent DPS output without entering melee danger zones. In a sustained damage format where you want to build a large champion army, range matters more than tankiness. A dead champion deals zero DPS, and Sirion's range keeps it alive longer than melee champions.

Sirion is fragile (the community describes it as "made of paper"), but range keeps it safe in most Kraken scenarios. If your Sirions are dying too quickly, Nexus is the alternative. Nexus is tankier but has lower overall DPS. Use Nexus if you need it, but Sirion is the ceiling pick.

Summon Gate (Ultimate)

Summon Gate is the recommended ultimate for Kraken. The critical technique is placement: put it BEFORE multiplier gates and fuel gates so that the mobs it summons flow through those gates and multiply. This dramatically amplifies your damage output during the timed battle.

This placement principle is simple but easy to forget in the heat of a run. Make it a habit: Summon Gate goes upstream of multiplier gates, every time.

Advanced Mechanics That Affect Kraken Performance

Understanding these mechanics is the difference between passively participating and actively maximizing your Sparks per ticket.

The Damage Window

Kraken fights do NOT work like regular campaign levels. In a normal level, you defeat the enemy base and then a short looting phase generates your rewards. Kraken is different; it plays more like a Pinata level. Each battle is a timed window (roughly 1 minute) where the Kraken is attacking you and your goal is to deal as much damage to it as possible before time runs out.

There is no distinct "looting phase" after the fight. Your Sparks output is determined by the total damage you deal to the Kraken during the battle itself. Every mob, champion, and ultimate that is active and dealing damage during the fight window contributes directly to your score.

This means the entire fight IS the window. The tactical implication: you need to maximize your field presence and damage output throughout the battle, not save everything for a post-defeat phase. Build your champion army early, get your ultimates charged and deployed, and keep sustained damage on the Kraken for the full duration. A fight where you have 8 Sirions and 2 ultimates active for most of the window will generate dramatically more Sparks than one where you spend most of the time with only 2 champions on the field.

Think of it this way: every second of the fight counts equally. Lost DPS at any point in the battle is lost Sparks.

Ultimate Charging

Understanding how ultimates charge is essential for maximizing your damage output during the fight.

Ultimates charge primarily through champion kills, specifically finishing blows on enemy mobs dealt by your champions. Champion damage alone does not count; only the killing blow matters. Ultimates also charge passively over time, but champion kills are the primary accelerator.

This creates a powerful synergy loop that you should actively exploit:

1. The Extra Champion building skill spawns more champions on the field
2. More champions means more finishing blows on enemy mobs
3. More finishing blows means ultimates charge faster
4. More ultimates active during the fight means more damage and more Sparks

This loop is why the building skill allocation below prioritizes Extra Champion so heavily. Every additional champion on the field means more DPS and faster ultimate charging, which compounds into higher damage output across the full fight.

Building Skill Allocation

Your building skill point distribution directly affects Kraken performance. The community-recommended allocation follows a 2:1 Extra Champion to Ultimate Boost ratio:

For 4x Multiplier Size: push to 35 points. The larger multiplier gates amplify every mob that passes through them, which stacks with your Summon Gate placement strategy and maximizes your total damage output during the fight.

Multiplier Gate Timing Strategy

Since Kraken is a timed fight (like a Pinata level), you want to maximize your total damage across the full duration. Multiplier gates amplify your mobs' damage, so use them, but use them strategically.

In the early fight, focus on building your Sirion champion army and charging your ultimates. Once your army is established, start flooding mobs through multiplier gates to ramp up your sustained DPS for the remainder of the fight. The goal is to hit peak damage output as early as possible and sustain it.

The optimal flow:

1. Early fight: focus on champion accumulation. Let the Extra Champion skill spawn Sirions and start building your kill count for ultimate charging.
2. Mid fight: once you have a solid Sirion army and your ultimate is close or charged, start pushing mobs through multiplier gates to ramp damage.
3. Peak phase: deploy your Summon Gate (placed upstream of multiplier gates) and flood the field. Your full army of champions, multiplied mobs, and ultimate should all be dealing damage simultaneously.
4. Sustain this output through the end of the timer to maximize total Sparks.

An advanced technique used by top players: hold multiplier gates in the early fight to maximize Sirion buildup, then trigger a massive wave through gates timed with a Summon Gate activation for a synchronized burst that carries through the rest of the fight. This requires practice and familiarity with the timing of your specific loadout levels, but it represents the ceiling play.

Common Mistakes

• Skipping Clan Mission days. Every missed mission day during phases 1–6 means fewer tickets for the day-7 boss fight. Complete and claim missions daily, even if you can only log in briefly. Missing the day-7 fight window wastes every ticket you earned.
• Using speed builds. Alien/Bat with Triple Cannon produces fragile, fast mobs that die before dealing meaningful boss damage. Switch to the Big Bertha/Raccoon/Sirion/Summon Gate loadout.
• Neglecting ticket claims. Completing Clan Missions makes tickets available, but you must manually cash in to collect them. Unclaimed tickets are lost. Check in daily during days 1–6 to complete missions and claim every ticket.
• Slow-building your army. Since the fight is timed, every second without champions on the field is lost DPS. Get your Sirion army established as quickly as possible so they're dealing damage for the maximum duration.
• Ignoring Summon Gate placement. Summon Gate placed AFTER multiplier gates is a wasted ultimate. Always place it upstream.
• Not investing in Kraken-optimal units. Big Bertha, Raccoon, Sirion, and Summon Gate are high-efficiency upgrade targets that serve you across multiple events.
• Treating it like a regular level. There is no post-defeat looting phase in Kraken. Your damage output during the timed fight IS your score. Maximize sustained DPS throughout the entire battle window.
