3 hours/mana or psi

As two actions, you consume half a liter of blood from a creature that could cast spells that died within the last 24 hours. You can learn a spell with a mana or psi cost up to your mana limit or psi limit that the creature knew for the duration. Your GM determines the spell, though you can provide input such as “a higher mana spell”, “a spell that can protect me”, “a spell that can cause mass destruction”.
