As an action, you call forth a beast which appears in an unoccupied space that you can see within 18 meters. The beast assumes the form of a beast companion that you know, using 2 resources. You can learn a form that you have seen before and that you have detailed knowledge of and you can learn a number of forms equal to your proficiency bonus.
The creature has no stamina dice, but you can infuse it with stamina dice by expending mana or psi, up to your mana limit or psi limit. For each mana or psi you expend, the beast gains 3 stamina dice. The beast is friendly to you and your companions, and it disappears when it drops to 0 health or when the spell ends.
As a bonus action on each of your turns, you can mentally command any creature you summoned with this spell if the creature is within 90 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). You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.
You can use an additional resource for each additional mana or psi expended.
Faithful Beasts. You can expend 1 additional mana or psi to cast the spell as a reaction, which you take when you or an ally you can see within 9 meters of you is reduced to 0 health. The beast appears within 3 meters of the fallen creature, protects it from harm, and attack its foes.
You can expend 2 additional mana or psi to call forth another beast.
