You have learned to combine the runic magic system of the dwarves with your spells allowing you to create enchantments on anything you transcribe a spell onto. 

Arcane Quill

As a bonus action, you can magically create a Tiny quill in your free hand. The magic quill has the following properties:

• The quill doesn't require ink. When you write with it, it produces ink in a color of your choice on the writing surface.
• The time you must spend to copy a spell in to your spellbook equals 2 minutes per spell level if you use the quill for the transcription.
• You can erase anything you write with the quill if you wave the feather over the text as a bonus action, providing the text is within 5 feet of you.

Runic Apprentice

Starting at 2nd level you can use your Arcane Quill to write spells onto any nonliving item. The quill can only transcribe spells (at base level) equal to or less than the maximum level of spells you can cast. When you transcribe a spell onto anything (other than a spellbook) you may spend up to 8 hours transcribing a spell and the text will transforms into runes creating chargres of an enchantment effect (determined by DM) on the item that can be triggered a set number of times based on how many consecutive times you apply the spell. This process requires a catalyst of a value equal to or higher than the listed amount (DM has chart) which it consumes. The properties of the enchantment are determined by the spell that is transcribed as well as the amount of time spent transcribing and the value of materials consumed in the transcription process. Each item can only be enchanted with one spell at any one time and when the last charge is removed the item is destroyed.

Runic Journeyman

Starting at 6th level you have gained enough knowledge to now make your enchantments last indefinitely under most circumstances. This ability can only be used to transcribe spells with a range of self or touch, any other spell has either a chance to become a similar effect with a range of touch and an on hit trigger or fail to adhere (arcana check DC 10 + Spell level).

Your enchantments also gain a better resistance to destruction and now when the last charge is removed the item is only destroyed if you roll an 8 or lower on a d20 + your PB.

Runic Savant

Beginning at 10th level, you can now place multiple enchantments on a single item(see DM on how different spell react). How many an item can hold is determined by an items innate arcane durability (DM determines this). The transcription cost is multiplied by 10 for each spell effect after the first. Multiple spells applied this way must be done in one continuous process. Each spell after the first will also consume one spell slot of the appropriate level.

Runic Master

Starting at 14th level you can now transcribe spells onto items in a way that can be recharged and you can use spells no matter their range. The recharge rate is always determined by a roll each dawn gaining from 1 charge up to a maximum of 1/2 of the total charges possible. If the last charge of an item made this way is ever used, the user must make a d20 roll, if the result is lower than the maximum number of charges the item turns to dust and is lost.
