Every roll on Boulder
- +1% to +5% Range Expands the area that the equipped unit can cover.
- -1% to -5% SPA Lowers seconds per attack (SPA). Negative SPA is beneficial because attacks come out faster.
The range shows the possible value for that stat. The dice count on the equipment determines how many listed values can be rerolled or protected with a lock.
Who can equip Boulder?
Exclusive to Lady Giant (Envy)
This Unit Equipment uses the extra exclusive slot unlocked by the evolved unit.
When should you lock a stat?
Use an Equipment Lock only when one existing roll is already valuable for the intended unit. Locking a mismatched Physical, Magical, critical, range, or SPA stat increases future reroll cost without improving the build.
