Starfinder 2 RPG - Starfinder Alien Core

Inside Starfinder Alien Core , you'll find over 200 creatures, including science fantasy favorites like robots, spacefaring fey, and all-new dragons; alien beasts from friendly spiderlike empathnids to fearsome plantlike predator ksariks; and unique monsters that threaten the galaxy of Starfinder, like jinsul troopers and vicious Swarm subspecies. You'll also find legacy Pathfinder creatures with a scifi update, like nanite-infused algollthus, and Starfinder classics like akatas and laser wolves. These creatures cover all levels of play, from scavenging sluglike diathas to powerful Drift-dwelling spectra.

Starfinder Alien Core is the only book GMs need to add enemies and allies of all sorts to their Starfinder Second Edition game, providing enough aliens of all power levels and thematic niches to populate countless worlds. And since Starfinder Second Edition is fully compatible with Pathfinder Second Edition, every alien presented in this massive tome can pull double duty in Pathfinder campaigns with next to no adjustment.

• Over 200 individual alien writeups, including common foes, like glitch-spawning gremlins, robots programmed for assassination, and mindless cybernetic zombies, to unique creatures that can threaten even the most experienced interstellar explorers, such as Akiton's dreaded illumantula and the giant Castrovelian ooze known as the Terror or Ukulam!
• Four science-fantasy dragons, giving a new spin to adventure fantasy's oldest foes, representing the four magical traditions. Whether it's the divine cosmic dragon or primal host dragon, these beasts are sure to make a memorable experience with every encounter!
• New additions to classic RPG creature families like angels, devils, trolls, and giant worms.
• Representative combatants from some of the Starfinder setting's most iconic organizations, including the Azlanti Star Empire's Aeon Guards, the imperious Hellknights, nature-loving Xenowardens, the undead crew of the infamous Corpse Fleet, and more!
• Simple creature adjustments that allow you to customize a monster, tuning its power level or theme with just a few simple alterations. Dial up the tech level of fantasy creatures or the magical nature of scientific anomalies and keep your players on their toes!
• Guidelines for reading and using alien statistics, ensuring you get the most out of a creature both in and out of combat.
• Lists of creatures sorted by both type and level, making it easy to find the alien you need when you need it.
• Hundreds of beautiful full-color creature illustrations!
