Monster Manual III
Engulf (Ex): a glitterfire can flow around creatures that fit within its space as a standard action. It cannot make a slam attack during a round in which it engulfs. A glitterfire merely has to move over the opponents, affecting as many as it can cover. Opponents can make attacks of opportunity against the glitterfire, but if they do so they are not entitled to a saving throw. Those who do not attempt attacks of opportunity must succeed on a DC 14 reflex save or be engulfed; on a success, they are pushed back or aside (opponent's choice) as the spell moves forward. Engulfed creatures are subject to the full normal effect of the fireball and glitterdust effects each round on the glitterfire's turn, and are considered to be grappled.
Fireball (Su): a creature hit by a glitterfire's slam attack or engulfed by it takes 5d6 points of fire damage (reflex DC 14 half).
Glitterdust (Su): a creature hit by a glitterfire's slam attack or engulfed by it is blinded (will DC 13 negates) and covered in dust for 5 rounds, rendering it visible (if invisible) and applying a -40 penalty on hide checks.
Being unintelligent, glitterfire simply approaches any living creature, lighting it up and blinding it with glitterdust while erupting in tiny, but dangerous, explosions.
