Abilities 10 of Sorcerer
Forceful Wave
Sign
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.
Disarm
You must release your grip on the affected item for five seconds. Items that are fastened or otherwise secured remain as such.
Spray
A Spray ability includes the "Spray" prefix as part of the tagline and is delivered by throwing a single handful of packets all at once. Every character hit by a packet is affected, though no character can be affected more than once regardless of the number of packets that hit them.
