Critical Chance and Critical Damage are some of the most important stats in Sailor Piece, especially once you start pushing endgame content and dealing massive damage numbers. A strong crit build can completely change your damage output, letting you hit much harder against bosses, raids, and difficult enemies.

The problem is that many players only focus on one or two systems while ignoring other important upgrades that also provide huge crit bonuses. If your crit stats still feel low, chances are your build is missing several easy upgrades. This guide explains the fastest ways to increase Crit Chance and Crit Damage in Sailor Piece and shows which systems you should prioritize first.

Sacred Dominion Artifacts Are the Most Important

The biggest crit upgrade in the game right now comes from the Sacred Dominion artifact set. This should be your first priority if you are serious about building a max crit setup.

The full set bonus gives:

  • 15% Crit Chance
  • 22.5% Crit Damage

That alone is already extremely strong, but the real power comes from artifact substats. Properly rolled artifacts with additional Crit Chance and Crit Damage bonuses can massively boost your overall damage.

Because artifacts affect your entire account build, they become the foundation of almost every high-end crit setup. If your artifacts still have weak substats, fixing them should come before almost everything else.

Get Crit Chance Z and Crit Damage Z Rolls

The next major upgrade comes from stat rerolls on Sailor Island. You can directly reroll for Crit Chance and Crit Damage bonuses here.

For endgame builds, the goal is:

  • Crit Chance Z
  • Crit Damage Z

Together, these rolls provide:

  • 7% Crit Chance
  • 35% Crit Damage

Many players underestimate how important these rerolls are. If your rolls are still low-tier, you are losing a huge amount of free damage.

Max Out the Skill Tree Crit Branches

The skill tree also contains permanent crit upgrades that should not be ignored. Fully maxing the crit branches gives:

  • 5% Crit Chance
  • 15% Crit Damage

This system is one of the easier upgrades to complete because the progression path is straightforward. Once finished, the bonuses permanently improve your entire account.

Upgrade Infinite Tower, Boss Rush, and Crystal Defense

Sailor Piece Max Crit Guide – Fastest Way to Increase Critical Chance and Damage

Permanent game modes also provide huge crit bonuses once fully upgraded.

Infinite Tower Max Upgrades

  • 5% Crit Chance
  • 15% Crit Damage

Boss Rush Max Upgrades

  • 5% Crit Chance
  • 15% Crit Damage

Crystal Defense Max Upgrades

  • 5% Crit Chance
  • 15% Crit Damage

Combined together, these three systems give:

  • 15% Crit Chance
  • 45% Crit Damage

That is an enormous permanent increase and one of the biggest reasons why experienced players grind these modes heavily.

Don’t Ignore Guild Upgrades

Guild upgrades are another permanent source of extra crit stats. The Guild Board contains both Crit Chance and Crit Damage upgrades that improve your account further. Guild upgrades are not the first thing you should rush, especially compared to artifacts or permanent mode upgrades, but once you start min-maxing your build, they become very important.

Blessings Give Easy Crit Stats

Blessings only affect swords and melee weapons, but they are still one of the easiest ways to gain extra crit. A full B10 Blessing provides:

  • 25% Damage
  • 5% Crit Chance
  • 8% Crit Damage

If your main weapon or melee style still has a low blessing level, upgrading it can give an instant damage boost.

Mastery 500 Gives Massive Bonuses

Weapon and melee mastery is one of the newer systems that greatly improves crit builds. At Mastery Level 500, you gain:

  • 30% Damage
  • 30% Luck
  • 2% Crit Chance
  • 25% Crit Damage
  • 1.5x Damage Passive

However, these bonuses only apply to the weapon or melee style you are actively holding. The stats do not stack across all your equipment at once. Because of that, focus on mastering the weapon or melee build you actually use the most.

Best Power for Crit Builds

If your goal is maximizing crit stats, Colossus is currently one of the best powers available. A strong Colossus roll can provide:

  • Up to 10% Crit Damage
  • Up to 3% Crit Chance

Other powers can still roll decent crit bonuses, but Colossus remains one of the cleanest options for crit-focused builds.

Best Spec Passives for Crit

Spec passives are another important layer for endgame optimization. Some passives provide huge crit bonuses that help push your build even further.

Rampage

  • Up to 4% Crit Chance
  • Up to 10% Crit Damage

Executioner

  • Up to 4% Crit Chance
  • Up to 15% Crit Damage

Berserker

  • Up to 15% Crit Damage

Eclipse

  • Up to 3.5% Crit Chance

These passives become especially valuable once your core systems are already finished.

Which Relics Should You Use?

Relics can also improve your crit setup depending on what your build still lacks.

  • Crit Chance Relic Best if your crit rate is still inconsistent and you need more reliable critical hits.
  • Crit Damage Relic A solid option if your Crit Chance is already high and you want stronger crit scaling.
  • Damage Relic Usually gives the biggest final damage increase once your crit stats are already balanced properly.

In most cases, players with stable Crit Chance will benefit more from Damage Relics than stacking even more crit stats.

Index Milestones Give Permanent Crit Bonuses

The Index system is another major source of permanent account progression. Completing index milestones gives:

  • 3.5% Crit Chance
  • 25% Crit Damage

A lot of players ignore Index progression, but it now provides direct crit scaling in addition to damage and luck bonuses.


Crit builds are currently one of the strongest ways to scale damage in Sailor Piece. The important thing to understand is that crit does not come from just one system. Most endgame players stack bonuses from artifacts, rerolls, mastery, blessings, guilds, passives, relics, and permanent upgrades all together. If your damage still feels weak, chances are you are missing several permanent crit upgrades that add up over time. Once everything starts stacking properly, your build can reach extremely high damage numbers much more consistently.
