Acid surge is a racial encounter power available to genasi in the causticsoul manifestation. It is a move action power that allows the user to shift through other creatures' spaces and attack those creatures for acid damage.
Acid surge was introduced in the "Abyssal Genasi" article by Peter Schaefer in Dragon #380.[Dr380:19]
A character with the Foul Torrent feat can shift up to his or her full speed, instead of half his or her speed, as part of acid surge's effect.[Dr380:21]
The soul of erosion paragon path's Union of Blessed and Cursed Waters feature allows a character to manifest both watersoul and causticsoul at the same time, allowing the use of both acid surge and swiftcurrent in the same encounter.[Dr380:23]
