Base Class: Sorcerer
Where most sorcerers derive their powers from bloodlines or the various planes and realms of the multiverse, your talents are born from the Weave, the raw magical "fabric" that permeates the multiverse and provides all realms, planes, and entities with their magic. While the Weave was "destroyed" by the Blue Breath of Flame/ Spellplauge event in the Year of Blue Flame 1385 DR; as the Weave is the raw magic of the multiverse, it cannot be truly destroyed and has slowly repaired itself over the eras.
The magic you wield is powerful and raw, as you utilize very fabric of magic itself in your spellcraft.
Web of Magic
1st level Woven Will feature
To the Weave, all magic is the same and through your connection to it, you gain access to magic that would otherwise be unavailable to you.
Gain access to two cantrips and two 1st level spells from any other spellcasting class. At the following levels you gain access to two spells of the given level: 3rd level grants two 2nd level spells, 5th level grants two 3rd level spells, 7th level grants two 4th level spells, 9th level grants two 5th level spells.
Soul Splinter
2nd level Woven Will feature
Your soul is infused with the power of the Weave and can be splintered to grant temporary access to extra magic.
Once after each long rest you can chose to use a sliver of your soul to regain a sorcery point.
Metatation
6th level Woven Will feature
By focusing on your connection to the Weave you gain access to further access to the Weave's power.
You regenerate 1 sorcery point after finishing a short rest. At 20th level when getting the Sorcerous Regeneration feature you regain 5 sorcery points.
Overcharged Magic
14th level Woven Will feature
Your connection to the Weave has deepened and grants you more power than would otherwise be possible.
Can use any 2 metamagic options on a spell regardless of if the option specifies otherwise. You must expend a number of sorcery points equal to the combined cost of both options.
Spellfire
18th level Woven Will feature
You and the Weave are one and any damage done to you damages the Weave. In response the Weave grants you emergency access to its power as a method of defense.
Whenever you are hit with an attack you regain 1 sorcery point.

If anyone comes across this and has suggestions I would appreciate them. I wanted a subclass that focused more around sorcerer's innate flexable casting and metamagic features. I'm already planning to change spellfire (18th level) to use a percential dice so that it's less powerful.
