Spellbound In Ink

With enough coin, a talented spell-caster, the appropriate gems, and high quality ink, anyone can have magic etched into their skin (and don't forget to tip your tattoo artist). Price is determined by the level of the spell you want, and the gem you need is based on the school of magic. Your chosen spell-caster will also need to have knowledge of the spell in question in their own spellbook/personal knowledge of spells or be given access to the spell by you (either through your own spellbook or a found spell scroll)

Casting from your tattoo doesn't use a spell slot, and will use either your INT, WIS, or CHA score modifier to as both it's attack modifier and it's spell save DC (10+ (whichever is highest)). If a spell requires a material component with a cost to cast, you will still need that material. For any spell level higher than a cantrip, you will have to wait till a long rest to be able to use it again.

A body can only handle so many threads of the weave being sewn into them. You're limited to getting 5 tattoos in total. These can be of any level.
