/**@file  Each mephling has a breath weapon, the effect of which varies by the 
mephling's heritage. An air mephling's breath weapon is a cone of dust and grit 
(piercing damage), an earth mephling's breath weapon is a cone of rock shards 
and pebbles (bludgeoning damage), a fire mephling's breath weapon is a cone of 
flame (fire damage), and a water mephling's breath weapon is a cone of caustic 
liquid (acid damage). Regardless of the effect, a mephling's breath weapon fills 
a 15-foot cone, deals 1d8 points of damage to each target, and allows a Reflex 
save (10 + 1/2 mephling's Hit Dice + mephling's Con modifier) for half damage. 
A 1st level mephling can use his breath weapon once per day; a higher-level 
mephling gains one additional use per day for every four levels he has attained. 
If a mephling can use his breath weapon more than once per day, 1d4 rounds 
must pass between consecutive uses of the breath weapon.
