Default Spell Icon ID Reference
Spell Icon Duplicates
In the Default spell icon set, many new_icon ids render identical art: 130 of the 145 ids used by in-game spells collapse into the 19 groups below (the remaining 15 ids are unique). Icon_List shows one icon per group, labeled with the group's lowest id.
Spell pages always use the spell's true new_icon, not the group's lowest id: the in-game Alternate 1 and Alternate 2 icon sets (Options → Interface → General → Alternative Textures) assign distinct art to every id, so ids that look identical below are different icons for players using those sets. The duplication is a property of the Default skin only.
Each group shows every member id rendered from its own uploaded file, lowest (canonical) id first. Ids marked ≈ are stored as slightly different image files that render the same art.
