Tattoo of Power

This spell is a method of implanting spells into someone via tattooing them. You must cast this spell, followed immediately by the spell to be implanted in the tattoo (though this casting does not cause any of the spell's effects to occur, and requires all of the spell's components). You then begin to tattoo the recipient of the spell. When finished, the tattoo contains the power of the spell, which can be released simply by touching the tattoo and uttering a command word, decided by you before the completion of the process. Once the spell is cast from the tattoo, the markings of the tattoo fade and disappear almost immediately. The casting time of this spell is one hour for each level of spell to be tattooed, which is how long it takes to tattoo the recipient, as the initial casting of the spell takes no time.

When the spell in the tattoo is released, it operates exactly as if it were cast by you. If you implanted a 3rd-level spell using a 6th-level spell slot, then the released spell is the 6th-level version of the 3rd-level spell. The recipient of the tattoo may choose where and who to target for example, though uses your spell attack bonus and spell save DC is relevant. Otherwise, they are treated as the caster of the spell.

Tattoos can take a lot of space. For every level of spell implanted, a tattoo will cover a 2 inch square of skin. This limits the number of tattoos that can be drawn upon the average human body, though the exact number differs from person to person and should be decided by your DM should the need arrive. Up to four levels of spells can be inscribed on each average human arm, ten levels on the chest, and six levels on each leg. No more than four tattoos can be placed upon a single individual at any time.
