Is your feature request related to a problem?

Cadiro's Gambit (Primed Quiver) has the line "Each Arrow fired is a Crescendo, Splinter, Reversing, Diamond, Covetous, or Blunt Arrow", which is unsupported. The quiver currently calculates as if it only granted increased Attack Speed.

The Diamond Arrow is the one that matters for the DPS number: all its Hits are Critical Hits, with 60% increased Critical Damage Bonus. On a bow character with 29% Critical Hit Chance and a 4.28x Critical Damage Bonus, that Arrow alone is worth 903k Full DPS against 393k, so the item reads as far weaker than it is.

Describe the solution you'd like

The six Perandus Arrows are:

• Crescendo: Chain 6 additional times, 60% increased Damage for each time they have Chained
• Splinter: Split towards 6 targets
• Reversing: Pierce all targets and Return to you
• Diamond: all Hits are Critical Hits with 60% increased Critical Damage Bonus
• Covetous: enemies killed drop items with 600% increased Rarity
• Blunt: 600% increased Stun Buildup

Each Arrow is rolled independently, so averaging behaviours as different as Chaining and guaranteed Critical Hits into a single number is not meaningful. A config dropdown that picks which Arrow to calculate, in the shape of the existing "Random element mode" for modifiers that choose an element, keeps every number honest and leaves the default behaviour unchanged.

Describe alternatives you've considered

Applying all six at once, which would report a character that Chains, Splits, Pierces and always Crits simultaneously. That number does not exist in game.

Search the codebase for Cadiro's Gambit, Perandus Arrows, and the existing "Random element mode" handling. Trace how item modifiers and configuration choices reach the damage calculation, then determine how a selected arrow should affect its behavior while preserving the default; done means each arrow can be selected independently without combining incompatible effects.
