The Clever Craft

A long-forgotten technique, the Clever Craft is an ancient form of spellcasting that utilizes the magical potential of a caster’s own body to bolster their spells. Using specialized rituals and rare inks to inscribe arcane tattoos onto the skin, mages of the Clever Craft channel raw ethereum into their magic. These tattoos can also be used to store spells and other effects. Wizards who specialize in this form of magic are powerful foes, especially those who's skin is marked heavily by their Ethereum Tattoos.

Level 2: Ethereum Tattoos

When you select this subclass at level two, you learn how to craft magical ink and how to ritually tattoo your body with it, creating an Ethereum Tattoo. The ritual process of adding an Ethereum Tattoo takes an hour of strenuous labor and costs 50 gold pieces worth of alchemical ingredients. You determine the appearance of your Ethereum Tattoo. Once the ritual is complete and the tattoo is on your body, you may select one of the following schools of magic that your Ethereum Tattoo amplifies, as displayed on the Ethereum Tattoo Effect Table:

School	Effect
Abjuration	Whenever you cast an abjuration spell of 1st level or higher, you gain temporary hit points equal to twice the spell’s level.
Conjuration	Whenever you cast a conjuration spell of 1st level or higher, you may teleport a number of feet away equal to 5 × the spell’s level to a point you can see.
Divination	Whenever you cast a divination spell of 1st level or higher, you gain a bonus to the next attack roll, ability check, or saving throw equal to the spell’s level until the end of your next turn.
Enchantment	Whenever you cast an enchantment spell of 1st level or higher, you may force a number of creatures equal to the spell’s level within 30 feet of you that you can see to make a Wisdom saving throw against your wizard spell save DC. On a failure, a creature is charmed or frightened of you (your choice) until the end of its next turn. This effect ends early if a harmful effect targets the creature or one of its allies.
Evocation	Whenever you cast an evocation spell of 1st level or higher, you may deal force damage equal to your wizard level to a number of creatures equal to the spell’s level within 30 feet of you that you can see.
Illusion	Whenever you cast an illusion spell of 1st level or higher, you may force a number of creatures equal to the spell’s level within 30 feet of you that you can see to make an Intelligence saving throw against your wizard spell save DC. On a failure, you are considered invisible to the creature until the start of your next turn. If the spell was 5th level or higher, this ability ignores the effects of truesight.
Necromancy	Whenever you cast a necromancy spell of 1st level or higher, you may force a number of creatures equal to the spell’s level within 30 feet of you that you can see to make a Constitution saving throw against your wizard spell save DC. On a failure, a creature’s hit point maximum is reduced by a number equal to the spell’s level + half your wizard level for one hour or until the creature is the target of a spell or effect that removes curses, such as remove curse. Additionally, until the end of the creature's next turn, if it would regain hit points, you regain those hit points instead.
Transmutation	Whenever you cast a transmutation spell of 1st level or higher, you may choose a number of creatures equal to the spell’s level within 30 feet of you that you can see. Those creatures' movement speed is either halved or doubled (your choice) until the end of their next turn. If a creature is unwilling, it must make a Constitution saving throw against your wizard spell save DC to resist the effect.

Once an Ethereum Tattoo has been added to your body, it cannot be removed by any means, though it can be altered to produce a different effect by reperforming the ritual. You may have a number of Ethereum Tattoos equal to your 2 + your proficiency bonus at any given time, and you cannot have any identical tattoo effects.

Level 6: Spellstoring Tattoo

In addition to amplifying your spells, your tattoos can store raw ethereum in their ink. As part of a strenuous hour-long ritual, you can create a specialized Spellstoring Tattoo and place it on a creature within 5 feet of you. During this process, you may cast a spell of 5th level or lower. You determine the appearance of the Spellstoring Tattoo. As long as the tattoo is on the creature, it may cast the spell you stored when you created the Spellstoring Tattoo without expending a spell slot and using your spellcasting ability. If the stored spell requires material components, they must be provided when the tattoo is created. You may only have one Spellstoring Tattoo active at a time. Once the stored spell is cast or you attempt to create another Spellstoring Tattoo, the previous Spellstoring Tattoo fades and ceases to exist.

Level 10: Alternative Interpretation

Other mages have a binary understanding of magic compared to you, to the point where you can reinterpret the intent of their spells. When you see a creature cast a spell of first level or higher within 60 feet of you, if the spell is of a school that you have a corresponding Ethereum Tattoo of, you may trigger that tattoo's effect as a reaction. You may use this ability a number of times equal to your Intelligence modifier per long rest.

Level 14: Grand Design

Your body has become a wellspring of ethereum, and as such, your tattoos grant you additional passive strength. While you have the maximum amount of Ethereum Tattoos for your level, you may select one of the following benefits whenever you complete a long rest:

• Your AC while not wearing armor is 13 + your Dexterity modifier.
