Rune Caster (Charisma)

Over the course of your adventures you have studied the art of rune magic to aid in your spellcasting, gaining the following benefits:

• Your Charisma ability score increases by 1
• When you cast a spell that deals damage or restores hit points, as a bonus action, you can treat any roll of 3 or lower as a 4. You can do this a number of times equal to your proficiency bonus before you must complete a long rest.
• You learn the spell Glyph of Warding and can cast it once without expending a spell slot, using the Spell Glyph version only. Casting Glyph of Warding in this way acts as if you had casted it using your highest level spell slot. Once you have done so, you must complete a short or long rest before casting Glyph of Warding in this way again. Your spellcasting ability for Glyph of Warding is Charisma.
