No spell slots. Load your Codex Rig each Long Rest with Techniques; the book pays the Burn so the body doesn't have to.
The wizard houses fell in the Pulse Wars. The Codex Rig is what survived — a worn book, often cabled to the spine, that holds Techniques in writable physical form. Imperial Citadel-9 runs the only sanctioned Cipherbound training program. The ones who didn't train there are usually being hunted.
Cipherbound — Shatterds Sourcebook
Key Mechanic: Codex Loadout
Each Long Rest, load up to (Wizard level + INT mod) Techniques into the Codex. The Codex absorbs Burn before it reaches you. Any loaded Technique can be cast at any tier you can pay for.
Essa Interaction
Standard vial + Feedback Save. The Codex Rig absorbs Burn before it reaches the caster. No spell slots — the Onan Technique catalog replaces the wizard spell list.
