Feather bonuses & resourcesHow to use

Feather Simulator

Plan feather combinations for each statue in Ragnarok Origin Classic and compare total stat bonuses and resource requirements. Create plans on this device, or sign in to save them to your account.

  1. Choose statues, feathers and levels.
  2. Check set effects, total bonuses and missing resources.
  3. Compare plans and share a configuration or overview image.

How the comparison works

Stats are added from the existing data for each selected feather and level. Set effects are calculated separately for each statue before combining totals. Resource needs use cumulative level costs; select an owned-resource profile to check shortages.

Example: copy plan A to B, change only one feather’s level and use the same owned-resource profile. Compare final stats, set effects and resource requirements before deciding to upgrade.

This compares feather configurations, not full combat damage. When a value has conflicting sources or awaits confirmation, check the displayed notes against the actual game values.

Tutorial and result interpretation

Choose a configuration, then compare bonuses and resource needs. Each statue’s feathers and sets are calculated separately before totals are combined. Presets are starting references to adapt to your class and resources.

Follow these steps

  1. Copy and name a reference plan. Check each statue’s feathers, fixed slots and levels; before replacing a feather, check whether its set effect will change.
  2. Select your owned resources and inspect cumulative costs and shortages by material type. Different resource pools cannot offset each other; total cost is not the same as your shortage.
  3. Copy A to B and change one feather or level at a time. Check whether you are saving a device or account plan and confirm visibility before sharing.

Worked example

In B, raise one feather in the same slot by one level while keeping all other statues and owned resources unchanged. Compare total bonuses, added cost and remaining shortages. When replacing a feather, compare the set effects too, rather than only its individual stats.

Important limits

This is not a full combat-damage simulation. Sets are evaluated per statue. Check source differences or unconfirmed values against the notes and game. An unavailable share does not open the author’s private plan.
