Double Ruler Kenpachi is not just a lucky pull, it is one of the most destructive setups you can achieve in Universal Tower Defense. This guide explains why Ruler is so strong on Kenpachi, how the build works in real gameplay, and whether it is actually worth chasing for normal players.
What the Ruler Trait Does and Why Double Ruler Is Insane
Ruler is widely considered the best trait in the game because it gives three of the most important stats at once:
• Increased damage
• Reduced cooldown
• Increased range
When you roll Double Ruler, those bonuses stack together, resulting in absurd stat scaling. On Kenpachi, this matters more than almost any other unit because his kit heavily rewards raw damage, range coverage, and cooldown efficiency.
With Double Ruler, Kenpachi gains around 40% extra range, massive damage boosts, and much faster attack cycles. This turns him from a slow, heavy-hitting unit into a full-map threat.
Why Kenpachi Synergizes Perfectly With Ruler
Kenpachi already has one of the strongest passives in the game:
• Ignores 50% of elemental restrictions on armor and hyper armor
• Slows enemies in his range
• Increases damage enemies take while affected
These passives alone make him strong, but Ruler amplifies everything he does.
Because Kenpachi ignores armor and hyper armor, he remains effective against bosses that completely shut down most DPS units. When you add Double Ruler on top of that, he does not just survive those encounters, he deletes them.
This is especially noticeable in high-HP boss challenges where even Kyito struggles to deal meaningful damage.
Damage and Range Scaling Explained
With Double Ruler and proper relic investment, Kenpachi’s stats reach absurd levels very quickly:
• Over 1.5k damage on placement
• Scaling into 17k–28k damage per hit when fully upgraded
• Full AoE hybrid coverage
• Extremely high DPS despite a slower SPA
Because his attacks hit everything in range, slower attack speed is not a weakness. Each hit applies slows, debuffs, and massive damage across the entire wave.
When combined with support buffs like Meiku (Idol), his range and damage scale even further, allowing him to control entire sections of the map alone.
Relics and Why They Matter So Much
Relics play a huge role in making Double Ruler Kenpachi feel broken. High-level mythic relics can easily double his effective damage output.
When relics provide both flat damage and percentage damage bonuses, they stack multiplicatively with Ruler traits. This is why the showcase damage looks unreal compared to a standard Kenpachi build.
Without strong relics, Double Ruler is still powerful, but with maxed relics, Kenpachi becomes one of the most oppressive units in the game.
Performance in Real Matches (Not Infinite Mode)
One of the most important things shown in the video is that Kenpachi was showcased in a regular challenge, not infinite mode. This matters because infinite mode can exaggerate unit strength.
In normal gameplay, Double Ruler Kenpachi:
• Shreds armored bosses
• Controls waves through slows and AoE
• Provides indirect support by increasing enemy damage taken
• Scales fast enough to carry difficult challenges solo
Against shielded bosses, where many top-tier DPS units struggle, Kenpachi remains effective due to his armor-ignoring passive.
Kenpachi vs Kyito – Honest Comparison
Kyito is still widely considered the best DPS unit overall due to his insane scaling and Virtual Realm synergy. However, Kyito has one major weakness: he is not hybrid.
Kenpachi fills that gap perfectly.
In content where hybrid targeting is required or where armor and hyper armor are dominant, Double Ruler Kenpachi can outperform Kyito. This makes Kenpachi one of the best complementary carries in the game rather than a replacement.
If Kyito is raw damage, Kenpachi is damage plus control.
Is Double Ruler Worth Chasing?
For most players, chasing Double Ruler is not necessary. It is extremely expensive and relies heavily on luck or heavy reroll investment.
However, if you already own Kenpachi and plan to main him long-term:
• Single Ruler is already top-tier
• Double Ruler turns him into an endgame monster
• Investment pays off in challenges and boss content
If you are free-to-play or early-game, focus on getting one good Ruler roll, not two.
Double Ruler Kenpachi is one of the strongest builds currently possible in Universal Tower Defense. His armor-ignoring passive, full AoE hybrid damage, slows, and debuffs combine perfectly with Ruler’s stat boosts.
He excels in boss fights, challenge modes, and late-game progression where other units fall off.
