You can spend 10 minutes to call forth an animal from the wilderness to serve as your faithful companion, known as an animal companion. The animal moves from the wilderness to a space within 10 meters of you and uses the statistics an animal companion. You can attempt to call forth an animal that you have detailed knowledge of.

Reduce your stamina and maximum stamina equal to double your Aptitude Bonus. Your companion is augmented to half the amount of stamina. Your companion is friendly to you and your companions.

Any creature you animated with this spell acts after your turn. You can mentally command the creature if it is within 20 meters of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). The creature(s) will generally follow any specific verbal commands that you issue to them if the likely outcome is in accordance with its desires (no action required by you). For example you may command it to guard a particular chamber or corridor, explore the room ahead, or to attack a specific creature. If you don't issue any commands, they defend themselves from hostile creatures, but otherwise take no actions.

If your companion is ever slain or chooses to leave you, you can call forth another animal.
