Abilities 42 of Sorcerer
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.
Imbue Element
You may call the damage type stated by the user (either Fire, Ice, Prime, Shock, or Tox) whenever you inflict damage. You may only ever call a single damage type per attack, regardless of how many you possess. The effect ends after you rest.
Burst
A Burst ability includes the "Burst" prefix as part of the tagline and affects all characters close enough to hit or be hit by you in melee at the time it is called. The ability cannot be avoided or blocked, though countering and immunity apply normally. If the effect is beneficial, you may choose to affect yourself as well.
