Summary

Fixed inconsistent spell duplicate handling between compendium and homebrew spells in D&D Beyond imports. Previously, homebrew spells would unconditionally overwrite existing spells with the same name, causing unprepared homebrew versions to replace prepared compedium versions. The fix unifies duplicate handling logic so both spell types follow the same rules for prioritizing prepared spells and comparing spell attack bonuses/DCs.

Changelog Entry

Fixed homebrew spells incorrectly overwriting prepared compendium spells during D&D Beyond character import.
