Spring Thórr Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (23) HP Superbane ★★★★☆
Atk (10) Attack Boon ★★★★★
Spd (3) Spd Bane ★☆☆☆☆
Def (10) Def Boon ★★★★★
Res (10) Res Boon ★★★☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Def / -Spd

The best IVs for Spring Thórr are +Def and -Spd. Boosting Def improves her Def check on her World Destroyer's Hardy Bearing effect, which is more valuable than any other benefits the other stat boons provide.

Spring Thórr's Spd is a clear dump stat and can be safely taken as a bane.

How to Use, Explanation
