Runecasting

When you take the following feat, you gain the following:

• Proficiency with Runecaster's Tools
• Ability to inscribe magical runes onto the surface of a creature or object. In order to inscribe a rune, you must expend a spell slot and one minute per spell level. The spell's potency is stored in the rune. Runes fade at the end of a long rest. The spell stored in the rune can be activated by you or any other person you designate at the time of inscription by speaking the command word. The activator must be within range (30 feet) of the rune to activate it. All spells use the rune as the origin for determining range. If the spell has a target of Self, the rune is instead the target. Upon activation, any attack or save required for the spell uses the Runecaster's spell attack modifier or spell save DC.
• The activation range of an inscribed rune doubles when you reach 5th level (60 feet), 11th level (120 feet), and 17th level (240 feet). 
• You can have additional runes inscribed at one time when you reach 5th level (2 runes), 11th level (3 runes), and 17th level (4 runes).
