Marionette Strings

3rd-Level Artificer Feature

You learn to fashion the strange Strings that mark you as a Puppeteer. When you finish a long rest, you can use your weaver's tools to construct a set of Marionette Strings, usable only by you. As an action, you can cause your Strings to fly out and magically attach to a willing creature within 30 feet. You must have a free hand to use your Strings.
While a creature is attached to your Strings, you gain the features listed below. Your Marionette Strings detach after 1 minute, if you use a bonus action to detach them, or if you and the creature are ever more than 30 feet apart.
You can attach your Marionette Strings a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses when you finish a long rest.
Corrected Strike. When the attached creature makes a melee attack, you can use your reaction to have them re-roll their attack roll, and they must use the new roll. You must use this reaction before you know if the attack hits or misses.
Channel Spell. As an action on your turn, you can cast an artificer spell as if it originated from the attached creature. If the spell requires concentration, you concentrate on it.
Puppeteer's Guidance. When the attached creature makes an ability check that uses a skill with which you are proficient , you can grant them a bonus to their roll equal to your Intelligence modifier (minimum of +1).
Strange Movement. As a bonus action on your turn, you can move the attached creature a number of feet equal to 5 times your Intelligence modifier (minimum of 5 feet). This movement does not provoke opportunity attacks.
