Draconic Rune Casting

You have unlocked the basic tenants of draconic rune casting. You gain the following benefits:

• You learn two draconic runes of your choice. These runes can’t be master runes.
• You learn the master runes up to the highest level of spell you can currently cast. As you grow in power and increase in level, you automatically learn the master runes for each spell level you can cast.
• You can inscribe draconic runes you know on objects and empower those runes with your magic when you finish a long rest. You can have a number of empowered runes at one time equal to 1 + your proficiency bonus. You can use empowered runes to replicate spells.
• You can magically mark an inscribed rune to use as a spellcasting focus for your spells.
