The Velan Codex

Composites: named threads

Any two learned spells can be threaded into one stroke per thumb (Codex section 6). An unnamed thread adds both effects together, then multiplies by 1.2, and gets 85% of the two breath windows added together. A named thread overrides that with its own effect. Players never invent threads: every pair is castable once both parts are learned. "Discovery" below is where the game names the thread and shows its effect, through a teacher, a fragment or the first time it is cast.

In the field it undoes a stilling1,360 ms#FFE08AAct 3, Corran, the climax. The event is called the Unstilling; the thread is Thaw. It is Repel because Repel can never be sealed and every player has it (Story Bible: an Evane spell into a Facet spell in one stroke).

It replaces this tab's earlier Stillhold (Facet Seal into Linger)Thornshield (Coil into Facet Seal), 0.55: over the 0.30 line, so it needs a recognizer check

"Nearest look-alike" is the most similar other two-spell chain, with that chain's shape score against a perfect draw of this thread (see "Shape overlaps"). A score below 0.30 means a perfect draw of this thread is not recognized as the other chain at all.
