This focused spell requires the gills from a fish. The
mage splashes water onto the gills and then breathes through them, casting the
spell on his third breath by pointing at the target character.
The effect value is the maximum number of kilos of
water (10 kilos) converted to air when the recipient of the spell breathes
underwater. This represents about eight full breaths, more than enough for a
normal round. A panicked or strenuously active character may breathe more often
than this, and water will bubble through to be inhaled, causing damage. The
gamemaster rolls a bonus number, interpreting the bonus as result points of
damage.
A character on land suffers no ill effect from this
spell, and the spell will remain active for the duration. The recipient
controls the duration of the spell.
