Trevo

Clover is a B Tier support card granting Luck +10 at cost 2. Luck directly increases Critical hit rate — the defining mechanic of Heaven Sword builds. As the Heaven Sword evolution component, Clover is mandatory in Cross/Critical-oriented builds.

With Triple Damage, high Critical rate creates the highest single-activation damage ceiling in the game.

Clover + Cross → Heaven Sword

In Heaven Sword runs, secure both Clover and Cross early. Whichever arrives first, hold and wait for the other.

• Cost-2 Luck +10 = direct Critical rate increase
• Required Heaven Sword evolution component
• Foundation of Luck-management builds
• Critical + Triple Damage compound creates maximum burst ceiling

• Cross: direct Heaven Sword evolution component
• Heaven Sword: post-evolution Critical rate further amplified
• Fortune Arcana: Luck addition stacks Critical rate higher
• Lucky Leaf relics: additional Critical rate stacking

General: B / Heaven Sword builds: Mandatory

Standalone effect rates accurately at B. Combined evolution value for Heaven Sword and Critical-build foundation justifies mandatory status in those runs.
