Looking through the system-specific tags for 5E, I've noticed that there are a few more I'd like to see:
- Spell Level (1st, 2nd, etc.)
- Spell School (Abjuration, Conjuration, etc.)
- Spell Components (V, S, M)
- Missing PC races from published 5E books (Genasi, Goliath, Aasimar, Firbolg, Tabaxi, Triton, Bugbear, Yuan-ti)
I'm hoping these can be added by the December update so they'll be available for users making use of the Game System Conversion feature.
