  You transfer some of your currently available spells, and the ability to cast them, to another creature. Only a creature with an Intelligence score of at least 5 and a Wisdom score of at least 9 can receive this boon. Only bard spells from the schools of conjuration (healing), enchantment, and transmutation can be transferred. The number and level of spells that the subject can be granted depends on its Hit Dice; even multiple castings of imbue with spell ability can't exceed this limit.
  As part of the casting, the caster must shed some of their blood (or an equivalent humor). If the caster isn't susceptible to bleed damage, regardless of the reason, they can't cast blood song. For each spell that is imbued using blood song, the caster loses 5 hit points, which can't be regained by any means until the spell ends or is discharged.

5 or higherOne or two 1st-level spells and one 2nd-level spell
The transferred spell's variable characteristics (range, duration, area, and the like) function according to your level, not the level of the recipient.
  Once you cast imbue with spell ability, you cannot regain the slot used to cast it until the recipient uses the imbued spells or is slain, or until you dismiss the blood song spell. If the number of 4th-level spells you can cast decreases, and that number drops below your current number of active blood song spells, the more recently cast blood song spells are dispelled.
  To cast a spell with a verbal component, the subject must be able to speak. To cast a spell with a somatic component, it must be able to move freely. To cast a spell with a material component or focus, it must have the materials or focus.
