Leyline Blooded

By attuning to a magical artifact, simply witnessing it's power, or even by taking a small sip, the Leyline Blooded are one with a never ending communal well of magic from a goddesses blood - aptly named the Spellpool.

Spell Call

At 1st level, you tap into the arcane spellpool to gain a unique ability granted to you that enhances your spells.
Once per long rest, you can cast a spell at the highest level you know from any spell list up to a maximum of 4th level spells. Once you grow to 6th, 14th, and 18th level you gain additional uses on each respective level.

Demonic Arm

You've got this terrible demon arm because of your lust for power, you idiot. But at least it gives you a few cool spells.

Magesight

You can see magic as if it was plain text written in a wispy smoke on and around a target that is affected by magic. You immediately know if a spell is affecting a creature or if they have magical abilities by succeeding on an INT (Arcana) check versus their spell save DC.
You also gain expertise in the Arcana skill.

Spell Conduit

At 6th level, your spell slots and other spell slots become a tangible source of energy.

• Spell Siphon: As a reaction, you can spend 3 sorcery points to cast Counterspell at 3rd level. After you successfully counter a spell using this ability, you regain 1 sorcery point.

• Magus Gift: As a bonus action, you can gift an ally within 60 feet a spell slot. This costs 1 sorcery point per level of the gifted spell slot. (Maximum 5th level spell slot)

• Spellplague: As an action, you can spend 3 sorcery points to force a target of your choice within 30 feet to make a CON saving throw against your spell save DC or lose one spell of the highest level they currently have available.

Enigma

When you cast a spell, you become ethereal and gain the ability to pass through solid objects as long as they're less than 5' thick and not made from lead. You can choose to move before or after you cast the spell and can move through living creatures, if a creature makes an attack of opportunity while you have this ability active, they have disadvantage on the attack roll.

Arcanus

At 18th level, you gain the following abilities as you learn to master the abilities you are granted from the Spellpool.

• Spellblock: As an action, you can use 5 sorcery points, to target a 20' cube. All creatures within the cube must make a constitution saving throw equal to your spell save DC. If they fail, they are affected by this ability, otherwise they are fine.

When a creature casts a spell while under this ability, you regain 1 sorcery point and they take 1d6 force damge for each spell level they cast the spell from.

• Epimancy: When you cast a spell using your "Spell Call" ability, you can now cast that spell using higher level slots with your own spell slots instead of casting it for free at a lower level.
