Sorcerous Origin - Weave touched
Your abilities were granted by the primal magic of the weave. You might have endured exposure to some form of raw magic, perhaps you were involved in a large convergence of magical energies or perhaps you were blessed by a powerful deity that can rewrite the fabric of the weave. Or your magic could be a fluke of your birth, with no apparent cause or reason. However it came to be, you have been granted sight beyond sight and have learned to use this to your advantage.)

Eyes of the Weave

Starting at 1st Level you sense the presence of magic within 30 feet of you. You see a faint aura around any visible creature or object in the area that bears magic. This ability can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.

Magical Transcription

When you see a creature within 60 feet of you casting a spell of 1st level or higher, make an ability check using your spellcasting ability to decipher the spell. The DC equals 10 + the spell’s level. On a success, you can determine the name of the spell, the school of magic, and the spell's target (if any). When you succesfuly decipher a spell of 1st level or higher using your Magical transcription class feature, you can use your reaction and add it to your spellbook if it is of a spell level you can prepare.

Weavebook

At 1st level, you have a spellbook. Your spellbook is the repository of the spells you have deciphered with your Magical Transcription class feature. You may only add spells to this to your spellbook using the feature Magical Transcription.

Preparing Spells
In addition to the spells gained from your base class you are able to prepare additional spells that are available to cast. Each of these spells counts as a sorcerer spell for you, but it doesn't count against the number of sorcerer spells you know. The spells must be of a level for which you have spell slots. Whenever you complete a long rest, you can replace one spell prepared using this feature with another spell in your spellbook. To cast one of these spells, you must expend a slot of the spell's level or higher. You regain all expended spell slots when you finish a long rest. You are able to Prepare two additional spells at level 1. The amount of spells that can be prepared increases by one when you reach 5th level (3), 11th level (4), and 17th level (5).

Copying a Spell into the Book. When you succesfuly decipher a spell of 1st level or higher using your Magical transcription class feature, you can add it to your spellbook if it is of a spell level you can prepare.

The Book's Appearance. Your spellbook is a unique interpretation of how you percieve magic. For some it is Mathematical formulas and notations for others it is colors sounds or movement recorded in some way that is appropriate for the caster. Unlike a wizards spellbook it is not a physical object that can be lost or destroyed but is instead a manifestation of your knowledge that can be called upon. The form of the spellbook should be discussed and decided upon at character creation. (Some examples include Tatoos that glow while casting, a woven tapestry and in some cases a spellbook)
