Starmetal Eater

Source Alien Archive 4 pg. 116
Strange protoplasmic pests that subsist on the rarest of metals, starmetal eaters usually remain microscopic and innocuous. Yet when these creatures gorge themselves on a rich vein of naturally occurring starmetal or even items made of starmetal alloy—either of which they can detect at great distances—they experience a swift growth spurt and can reach several feet in diameter. Each starmetal eater fixates its diet on one specific type of starmetal, gaining strange abilities as its appearance and essence are suffused with its metal of choice.

Special Abilities

Temporal Dilation (Ex) A horacalcum eater slows incoming projectiles, and ranged attacks against it have a 20% chance of missing.
Temporal Stutter (Su) A creature struck by a horacalcum eater is staggered for 1 round (Fortitude DC 19 negates). If the target succeeds at the save, it instead gains a +10- foot enhancement bonus to each of its movement speeds for 1 round. A creature struck multiple times can be both staggered and accelerated by a horacalcum eater.
