Spell Conversion Station

The station crafts from a book, source gems, and obsidian. It looks like someone stained an enchanting table purple.

Put a caster tome in the slot. Click Add to Codex. The tome is gone. That glyph recipe is now a level-1 card under the Ars Nouveau tab.

Same glyphs, same spell. Two players converting the same Projectile + Break tome share one Codex entry. Add Amplify to one of them and you get a second card. That is how you keep “the cheap poke” and “the packed nuke” as two hotkeys.

The discovery bar for the Ars school is “how many unique published tomes exist,” including addon tomes. The grid only shows recipes you have personally converted. A custom tome that is not in those datapacks gets added to the total the first time someone converts it, so the bar cannot sit at 110%.

If Add to Codex does nothing, you did not put a real caster tome in, or Codex is missing from the instance.
