## 7. Subclass Flavor Prompts

Each subclass selection triggers a TwinBee narration line and a one-line flavor acknowledgment in the player's character sheet. Examples:

- **Champion:** *"You've chosen the old way. No tricks, no systems. Just you, and the blade, and the next hit. TwinBee approves of this directness."*
- **Arcane Trickster:** *"Magic in the hands of a Rogue. TwinBee considers this the universe's way of apologizing for giving you low HP."*
- **Necromancer:** *"Undeath as a tool rather than a state. TwinBee has opinions about this. TwinBee is keeping them to itself."*
- **Beast Master:** *"You and your pet, all the way down. TwinBee finds this genuinely moving and declines to be embarrassed about that."*
- **Gloom Stalker:** *"You were already good in the dark. Now you're better. TwinBee notes: the Underdark is waiting."*
