Rutilant Arena

A two-piece Planar Ornament set that raises CRIT Rate and boosts Basic ATK and Skill damage at 70% current CRIT Rate. Consider it for a wearer whose damage uses those attack types and can meet the threshold.

Introduced in v1.2

Rutilant Arena grants 8% CRIT Rate. At 70% current CRIT Rate or higher, it also increases damage dealt by Basic ATK and Skill by 20%. Its conditional damage bonus is specific to those attack types.

Understand Rutilant Arena

Useful when…

  • A wearer who deals damage through Basic ATK and Skill and reaches 70% current CRIT Rate.
  • A wearer who benefits from the 8% CRIT Rate even when below the conditional threshold.

What does the two-piece effect do?

It increases CRIT Rate by 8%. When the wearer's current CRIT Rate reaches 70% or higher, Basic ATK and Skill damage increases by 20%. The attack bonus is conditional and applies to the named attack types.

When does it fit?

Consider it for a wearer who relies on Basic ATK or Skill damage and can meet 70% current CRIT Rate. The 8% CRIT Rate applies regardless, but below the threshold the 20% damage increase does not.

Which other damage profile might fit better?

Inert Salsotto also gives 8% CRIT Rate, but its conditional 15% increase applies to Ultimate and Follow-Up ATK damage at 50% current CRIT Rate. Celestial Differentiator instead gives CRIT DMG and a temporary CRIT Rate boost through the first attack if current CRIT DMG reaches 120%. Choose based on the actual attack types and conditions involved.

What should you avoid?

Do not count the 20% damage increase below 70% current CRIT Rate, or apply it to Ultimate and Follow-Up ATKs simply because those attacks deal damage.

Limitations and tradeoffs

  • The damage bonus requires 70% current CRIT Rate.
  • The bonus is limited to Basic ATK and Skill damage.

Common mistakes to avoid

  • Counting the 20% damage increase before reaching 70% current CRIT Rate.
  • Applying the bonus to attack types the set does not name.

Effects and reference details
