Reroll Decision Calculator

Not a “reroll simulator” (competitors already have those). This is a “reroll decision engine” — input your current build and target, get data-driven advice on whether to keep rerolling and what to prioritize.

Height × Style Synergy Analysis

Boxing + 178cm = Good Combo

Balanced — good attack speed with decent reach. Solid all-rounder.

Recommendation: Prioritize height to 183cm+

Height affects reach, stamina, hitbox, damage, HP, and attack speed. 183cm+ is only 4% probability but significantly benefits Boxing.

Not recommended: Switching to Muay Thai

Muay Thai needs taller height to leverage kick reach. At your current height the benefit is limited — rerolling height first is more cost-effective.
