About the ROOC Feather Optimizer

The ROOC Feather Optimizer is a free build planning tool for Ragnarok Origin Classic. It helps players find the most efficient feather combinations for their ATK and DEF statues based on their actual pool inventory and chosen stat priorities. No guesswork — just enter your feather counts, set your priorities, and let the optimizer do the math.

How It Works

Feathers in Ragnarok Origin Classic are slotted into 10 statues — 5 ATK and 5 DEF. Each statue holds 5 feathers, and the combination of Yellow and Purple feathers determines which Raven's set bonus you receive:

• Raven's Hour (4Y + 1P) — Highest ATK multiplier. Best raw damage output at every inventory size. Recommended for most DPS builds.
• Raven's Prestige (3Y + 2P) — Balanced ATK and DEF bonuses. A versatile middle-ground option for hybrid builds.
• Raven's Plunder (2Y + 3P) — More Purple feathers provide stronger DEF stats on ATK statues. Best for tank or utility-focused builds with large Purple inventories.

The optimizer scores thousands of feather configurations against your personal stat weights — you decide whether PATK, IgnorePDEF, HP, PDMGRed, PvE DMG, or PvP DMG matters most. Results are sorted by score and show exact feather assignments, resonance tier, set bonuses, and total stat output for all 10 statues.

Feather Pools

Feathers are grouped into 6 pools. Your total copies per pool limits what the optimizer can assign:

• Light/Dark — Yellow MIX feathers. Provide PATK, MATK, PvPDMG, and PvPDMGRed.
• Time/Space — Yellow ATK/DEF feathers. Provide IgnorePDEF, IgnoreMDEF, PDMG, MDMG, HP, and PvE stats.
• Day/Night — Yellow ATK/DEF feathers. Provide IgnorePDEF, IgnoreMDEF, PvEDMG, PDEF, and PvEDMGRed.
• Sky/Terra — Yellow ATK/DEF feathers. Provide PATK, MATK, IgnorePDEF, IgnoreMDEF, and HP.
• 90SF Purple — Purple MIX feathers (Order, Truth). Provide PDEF, MDEF, PDMG%, MDMG%, and IgnorePDEF/MDEF.
• 25SF Purple — Purple ATK/DEF feathers (Valor, Faith, Glory, Justice, Grace, Soul, Virtue, Mercy). Provide specialized ATK or DEF stats depending on feather type.
