Spells gained
| Spell | How | Where | Required? |
|---|---|---|---|
| Coil | Learned at the end of the Prologue; Act 1 is where it's used: the road glint, the Ring, the Wyrm. | — | Yes (already known) |
| Mend | Taught by Sister Orla, hand over hand (a taught glyph, no fragment). | Halfway, scene 3.5 | No, but the quest log suggests it before the Wyrm |
| Brace | Taught by Aske, hand over hand; she traces but doesn't cast. | Sallowbank ferry, scene 6.3 | No |
Both match the Spell Set's "Learned" column (Brace: Act 1, taught by Aske; Mend: Act 1, Halfway, taught by a Tender healer). Act 1 adds no fragment.
Composites: with Repel, Coil, Mend and Brace learned, the prototype allows every two-spell chain, so Repel into Coil (34 × 1.2 = 41 damage and a 2.5 s stagger) is possible against the Wyrm before anyone in the story has taught threading. The Story Bible puts the first thread in Act 2 (Rook or Dace, Repel into Gale: Headwind). Question 2 settles it: chains wait for thread.taught.
