From Ars Magica
Applies Water Breathing (buff) to the caster, allowing them to breathe underwater. Casting is instantaneous. Unlike other water breathing abilities that instantly refill the breath meter, this one will pause the breath meter wherever it is, making the longer buff duration from higher Casting Modes necessary for longer underwater excursions. The duration is 10, 20 and 90 seconds for each casting mode.
1 x Water Essence when cast augmented.
Castable by Caster Block
