Capture Monster

To a monster trainer, a monster is any creature with a simple aura. A creature’s aura is simple when:

• the creature doesn’t have class levels. Creatures with class levels fundamentally change their essence—change what they are—giving them complex auras and, in some cases, changing their physical form entirely.
• the creature is not summoned, already captured, or gained through a class feature such as arcane bond, natural bond, or eidolon.
• the creature’s CR is equal to or less than the monster trainer’s level. A trainer’s essence may not be strong enough to direct a more powerful monster than her experience would allow, and such monsters can even prove unresponsive or dismissive of the trainer when called upon outside of stressful situations such as during downtime.
• the creature has an Intelligence score. Mindless (Int —­­) creatures lack discernible essence and must awaken (as the spell), be commanded by their creator, or somehow be persuaded (food and gentle sounds to coax oozes and vermin, for example) before they can be captured.
