Trait source and reroll rules
Traits are rolled using Trait Reroll Stones (earned through gameplay) at the Traits NPC inside building near parking lot. This page treats Ruler as a direct candidate only when it appears in the imported unit recommendation field.
Unit context links
Ruka is connected to DPS / Support and Legendary hubs so trait advice can be compared against similar rows instead of read in isolation.
Recommendation
Ruka currently lists Ruler in the imported recommended trait field. Treat this as the starting point before reroll spending.
Ruka is listed as a support row, so cooldown, range, income, or buff-friendly setup matters more than raw damage alone.
Reroll checklist
- Medium priority: compare role fit and account needs before spending expensive rerolls.
- Compare the trait effect to Ruka's role before spending Trait Reroll Stones.
- Recheck after Update 3.0 before rerolling a borderline or unmatched tier row.
Matched trait details
