As two actions, you call forth an acid elemental which appears in an unoccupied space that you can see within 10 meters. The elemental is an acid elemental companion, using 2 resources. The creature has no mana or stamina dice, but you can infuse it with mana, psi, or stamina dice by expending mana up to your mana limit or psi up to double your mana limit. For each mana or 2 psi you expend, the elemental gains 1 mana or 2 stamina dice. The elemental is friendly to you and your companions, and it disappears when it drops to 0 health or when the spell ends.
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.
You can use an additional resource for each additional mana expended.
You can expend 2 additional mana to call forth another elemental.
