Elemental 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.
2 Hits
You suffer two hits worth of damage.
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.
