Runecraft

Instead of scribing a spell scroll (see “Xanathar’s Guide to Everything”), you may instead imbue the spell’s power to a stone no smaller than 15 cubic inches.  The spell must be of a lower level than your highest known spell (i.e.: if you can cast 3rd-level spells, you can create a runestone imbued with a 1st- or 2nd-level spell).

The runestone is activated as a scroll, but instead of the verbal component, a somatic component is required.

If a druid chooses this feat, woodworker’s tool proficiency is used instead of mason’s tools proficiency, and the rune is carved into or from a piece of wood instead of stone.
