Spell
Thornshield
Thread: Coil into Facet Seal
Described in the Codex; there is no Data/Spells file for it yet, so no strokes to draw.
Elsewhere in the Codex
The spell roadmap (VEL-60) places all the optional spells above in Act 2 and decides which ship first. The Story Bible's example threads (section 7) are both here: Gale into Coil is Tempest, and Coil into Facet Seal is Thornshield, the first cross-side thread most players find on their own. Tempest and Bulwark already exist as data.
Lore: the door-mark is older than the Wardens (Story Bible section 2). Threaded into a Facet glyph it becomes the thing a mirrored seal can't reflect. It mixes the sides like Bulwark (Repel into Facet Seal) and Thornshield (Coil into Facet Seal), and it is the first thread anyone has used to mend rather than fight. Repel is the Evane half because it can never be sealed and every player has it.
From Walkthrough: Act 3 › Spells gained › Thaw, Repel into Pavilion Wake **(Idea)**
Spells: recognising a cast's drawing tier and whether a composite is cross-side; the composite effect
reflectNextAttackSeconds; a recognizer check, because the First Pair's stroke overlaps Thornshield (Coil into Facet Seal) at 0.55.
[ ] 26. Threads have names. Settled for now by VEL-63, confirm. Story Bible § 7 says a thread is named by its parts ("Repel into Gale"). Game data already has Bulwark and Tempest, and the tabs name every thread: Headwind, Tempest, Bulwark, Thornshield, Wellspring, Blight, Thaw, Rebound, Deep Cut and the First Pair. Recommendation: one-word names in data and the Spell Book (Repel into Gale is
headwind, flagcomposite.known.headwind), with the parts shown underneath. Update § 7 to match. Sources:story-bible.md § 7 Composites;walkthrough-act-2.md Q5;spell-roadmap.md Composites: named threads.From Walkthrough: Act 4 › Open questions for Ray, all tabs › Spells and casting
[ ] 38. The First Pair. Settled for now by VEL-63, confirm. Keep a new named thread, Brace into Facet Seal, from a reflected glyph in the Pane at dawn? Recommendation: keep it. It replaces the roadmap's Stillhold, keeps
#FFFFFFon purpose instead of the cross-side#FFE08A, and any cross-side thread is the fallback, so no player is locked out of Stop both. Its overlap with Thornshield (0.55) needs a recognizer check.

Threads. Headwind (Repel into Gale) is the first, taught by Rook or Dace in Act 2; Tempest (Gale into Coil) and Bulwark (Repel into Facet Seal) follow the lesson; Thornshield (Coil into Facet Seal) and Wellspring (Mend into Root) are Act 2's other named threads. Thaw (Repel into Pavilion Wake, 1,360 ms) undoes the stilling of Corran in Act 3; the scene is still called the Unstilling, and Aske casts Brace across the warp at the same moment. The First Pair (Brace into Facet Seal,
#FFFFFF) is Act 4's reflected thread and replaces the roadmap's Stillhold. Knell stays on hold.From Walkthrough: Act 4 › Continuity notes › What is now the same everywhere
Spells Gained: threads Tempest, Bulwark, Thornshield, Wellspring added; paragraph now says Gale into Coil is Tempest and Coil into Facet Seal is Thornshield (VEL-63 thread table)
9 (Thaw lore): "second named composite to mix sides, after Bulwark" → mixes sides like Bulwark and Thornshield (Thornshield is also a cross-side Act 2 thread)
Section 14 code needs: recognizer check for the First Pair's overlap with Thornshield at 0.55 (VEL-63 First Pair note)
"How difficulty climbs": Act 1 tools marked optional; Act 2 row set to the VEL-63 schedule (Gale, Facet Seal, Weigh main; optional set; Tailwind, Squall side; Bevel Lash only if both halves; threads Headwind, Tempest, Bulwark, Thornshield, Wellspring); Act 3 row (Linger, Hasten, Pavilion Wake main; Crown Surge fades; Toll, Recall, Prism Snare, Girdle Gate optional; Thaw, Blight, Rebound, Deep Cut); Act 4 "no new spell, only the First Pair"; typical ranges widened for the new easy fights (VEL-63 spell schedule)
Composites, Thornshield: look-alike "Brace into Facet Seal" → "The First Pair (Brace into Facet Seal)" (that chain is now a named thread)
Composites: Stillhold row replaced by the First Pair (Brace into Facet Seal, shield 40 + reflect next attack within 4 s, 1,190 ms,
#FFFFFF, Act 4 scene 4.12, look-alike Thornshield 0.55 needing a recognizer check) (VEL-63 threads)
