Starfinder Simple Template Grafts
Simple template grafts are designed to allow a GM to quickly and easily adjust a stat block in minor ways to represent new creatures. Most simple template grafts do little more than add a subtype, adjust one form of movement, and alter how a creature deals or takes damage. They can be used to create versions of creatures appropriate to specific environments or planes of existence. For example, the summon creature spell adds the astral, celestial, or fiendish simple template grafts to summoned creatures that are not already outsiders or extraplanar beings, which represents versions of those creatures native to other planes.
A GM can apply more than one simple template graft where appropriate, but in most cases she should not add more than two or three to a single creature. Even templates that seem opposed can be added to create specific kinds of monsters (a creature that lives in steam vents at the bottom of a boiling ocean might have both the aquatic and fiery simple template grafts, which could otherwise seem an unusual combination). Decide the order in which to apply the simple template grafts, and follow the instructions of each graft in order. A template graft with a CR requirement lists it in parentheses.
Simple template grafts can also be used to populate new worlds whose native flora and fauna haven’t yet been extensively detailed, or to distinguish a specific creature as a unique leader, mutant, or advanced version of common creatures. A GM can also choose to design new simple template grafts similar to these to create even more variety among the denizens of the galaxy.
|Aerial||Aerial creatures are native denizens of the Elemental Plane of Air, gas giant planets, or similar landless environments, and have unique adaptations to help them survive there.|
|Aqueous||Aqueous creatures are native denizens of the Elemental Plane of Water or similar landless environments, able to survive both in and out of water.|
|Astral||Astral creatures are natives of the Astral Plane, a vast silvery void between planes.|
|Celestial||Celestial creatures are natives of one of the good-aligned Outer Planes.|
|Cthonic||Cthonic creatures are native denizens of the Elemental Plane of Earth or underground environments, and they have adapted to exist in dirt and rock.|
|Cybernetic||A cybernetic creature has been augmented by technological implants (although the same simple template graft can be used to represent creatures augmented by biotech).|
|Entropic||Entropic creatures are natives of one of the Outer Planes where chaos is paramount. A GM can allow creatures summoned with the summon creature spell that would normally have the astral, celestial, or fiendish simple template graft instead have the entropic simple template graft.|
|Fiendish||Fiendish creatures are natives of one of the evil-aligned Outer Planes.|
|Fiery||Fiery creatures are native denizens of the Elemental Plane of Fire or habitats covered in fire, and they have unique adaptations to help them survive there.|
|Giant||Giant creatures are larger than typical members of their species, and might represent a subspecies that has grown to unusual size due to environmental conditions.|
|Miniature||Miniature creatures are smaller than typical members of their species, and might represent a subspecies that has shrunk down due to environmental conditions.|
|Phrenic||Phrenic creatures have minor innate mental powers, which they might have developed due to high levels of native psychic energy in their environments.|
|Resolute||Resolute creatures are natives of one of the Outer Planes where law is paramount. A GM can allow creatures summoned with the summon creature spell that would normally have the astral, celestial, or fiendish simple template graft instead have the resolute simple template graft.|
