Recently I watched the Evolution movie again, and it gave me an idea for a monster and encounter, that I’m currently incorporating into a new adventure, that goes further the court of the dryad queen (L3-T8) ends.
For simplicity the template and monster I have created isn’t exactly the same, but it does bring the idea into the game. And it would make a good recurring monster. The Starstone Evoled creature template that works well on any animal, fey, humanoid, magical beast, plant or vermin creature. While the Starstone Ooze, is a little menace that keeps the players on their toes, when they are eradicating these pests.
CREATING A STARSTONE EVOLVED CREATURE
A “Starstone Evolved” is an inherited template that can be added to any creature (referred to hereafter as the base creature). Most starstone evolved creatures are based upon animals, fey, humanoids, magical beasts, plants or vermin. A starstone evolved uses the base creature’s statistics and abilities except as noted here.
CR: Same as the base creature +1.
Alignment: Always Neutral.
Hit Points: A starstone evolved creature gains +2 hp per HD.
Defensive Abilities: A starstone evolved creature has immunity to fire and slashing damage, gains a weakness to cold and the following defensive abilities. But losses the any other elemental resistances it might have.
Reactive Regeneration (Ex): Whenever hit by an attack that deal fire or slashing damage, it regerates 5 hit points and gains 1 evolution point.
