Due to your time spent interacting with the weave through the casting of spells and use of magic items, the weave has decided to take on your eyes as a vessel, with some nifty bonuses to compensate.

Using the raw magic in your eye, you can peer into the realm of the weave at the cost of a charge. This allows you to see magical auras, overlaying them onto your regular vision for the  next minute or until dismissed. This allows you to see magical traps (glyph of warding, fire traps that use magic as fuel etc.) as well as outlines of creatures with magical abilities. The prevalence of their aura is determined by how powerful their magic is (a novice wizard may have a blue outline, a level 5 sorcerer may be like looking at a torch, a level 10 warlock like a campfire, a level 20 wizard like a bonfire while an archfey is comparable to looking at the sun). This however, comes with a drawback. If you view a creature with a higher spellcasting ability than you, your eye overloads dealing 1d8 force damage for every level they can cast higher than you and blinding you for 1d6 minutes. This also ends the ability. You can also overcharge your eye, which cost 3 charges. While overcharged, the weave begins to lash out, dealing you 2d8 force damage and anyone within 10 feet of you 1d10 force damage for every one of your spellcasting levels at the start of your turn. Additionally, the next spell you cast at half of your max casting level (or at your casting level if you're a half-caster) won't use a spell slot or materials and you can reroll the dice when applying healing or damage through the use of a spell, you must use the new roll. You can also cast a cantrip as a bonus action while overcharged. You have 5 charges which you regain 1d4 of at dawn.

 Additionally, you gain proficiency in arcana, learning the detect magic and identify spells and can cast them without expanding a spell slot as well. Once you cast either of these spells in this way you cannot cast them again until you finish a short or long rest.
