These characters are from a real 5e campaign, at this point of time in the comic, they're level 9, and everyone is monoclassed (as 5e is actually intended to be played)
- Konsi - Cleric (trickery) (this is my PC, which is why the comics mostly focus on her.)
- Toron - Rogue (swashbuckler)
- Mystery - Warlock (Fey patron (now), Tome)
- Sand - Monk (Open Hand, but he changed to Astral Self a bit later)
- Faelys - Staff of Power (also Wizard/Evoker)
Razira is an NPC sidekick built using the sidekick rules, with a little bit of paladin sprinkled in for flavour.
