Rune Master

Prerequisite: The ability to cast as least one spell, and an Intelligence of 13 or higher.

You are masterful in using runestones. You gain the following benefits:

• You become attuned to a rune stone in a short rest instead of a long rest
• You can use your own spell slots to reactivate a same level rune stone's spell slot
• You can cast one spell in a rune stone from 1 higher spell slot. Once you use this feature, you need to take a long rest to use it again
