Abilities 6 of Bondæ Græddi
You trigger a Sign ability just like a Spell ability. Instead of speaking an incantation, however, you use a free hand and count out tracing a symbol in the air or on a surface three times (e.g., "Signing 1, signing 2, signing 3"). Sign abilities can be used while Muted, but not with an arm that is Maimed.
You regain all of your hits after you finish resting. You must already be resting or begin resting immediately afterward to receive the effect, and it ends if your rest is interrupted.
