Sensitive Origins

Magic permeates the multiverse. This is undeniable, as is the sensitivity of other beings to the weave. Through study, bargaining or simple luck, being were born with the ability to control the weave to certain extents, with effects ranging from annoying to apocalyptic.

You were born sensitive to magic. Spells found greater purchase on you than others, and you took to spellcasting as a duck would to water. 

Arcane Sensitivity

Starting when you choose this origin at level 1, while conscious, you can make Arcana checks with advantage. You can use this feature to identify spells and spell-like effects.

In addition, you learn the Prestidigitation cantrip and can cast Detect Magic once per long rest without spellslots or components.

Vulnerability to Magic

Because you lack the structured disciplines and cautions often found with schools of Wizardry or prayers of divine magicks, you find yourself uniquely susceptible to the more malignant effects of spells and spell-like effects.

At 1 Level, you must resolve spells and magical effects cast upon you with disadvantage. If you take magical damage, then you are treated as having vulnerability.

Magic Sink

As you hone your sorcerous powers, you learn to use your vulnerability to magic to great effect, either sheltering your allies from waves of arcane fury or stealing blessings and boons meant for your foes.

At 6th level, When you see a creature within 30 ft become the target of a spell, you can spend a Reaction and a number of Sorcery points equal to the spell level (Cantrips count as level 1 Spells for the purposes of this feature) to roll against the caster’s Spell-Save DC using your spellcasting Modifier. On a Success, resolve the spell as if you were the target. In addition, when using this feature, you treat all dice rolls as having rolled maximum results.

Arcane Conduit

At 14 level, When you see a creature within 30 ft become the target of a spell, you can spend a Reaction and a number of Sorcery points equal to the spell level (Cantrips count as level 1 Spells for the purposes of this feature) plus one to roll against the caster’s Spell-Save DC using your spellcasting Modifier. On a Success, resolve the spell as if you cast it, selecting targets in range of you, using your spellcasting modifier if the spell calls for it, and adding Metamagic features to the spells.

Devour Magic

At 18 level, When you see a creature within 30 ft become the target of a spell, you can spend a Reaction and a number of Sorcery points equal to the spell level (Cantrips count as level 1 Spells for the purposes of this feature) plus three to roll against the caster’s Spell-Save DC using your spellcasting Modifier. On a Success, you can choose to gain a number of spell slots that add up to the level of the spell to use as your own or can gain a number of sorcery points equal to the spell level, to a minimum of 1.
