Raven Sorcerer

The Raven Sorcerer, that can summon a murder of Ravens empowers them to act as a conduit by absorbing the sorcerer's spells into themselves that transforms the ravens into elemental versions dealing magical damage and can assist in concentration and ritual spells. The ravens are willing to protect the raven sorcerer magically and take the damage inflicted on the sorcerer on to themselves even if at the cost of all their HP if the raven sorcerer so chooses. The Raven Sorcerer can master and empower their ravens more until able to magically transform into one.

(Temporary description until coming up with something more extravagant)

Summon the Dark Fey Wild's Murder Ravens

When the Sorcerer summons the 3 Ravens (Basic Rules, pg. 150) The sorcerer also empowers them naturally by adding the sorcerer's Charisma modifier to the raven's HP, AC, Stats, movement speed, HP,  To Hit, and Damage for each flock of 3 murder ravens summoned. The maximum flocks of Ravens that can be summoned per 1 Sorcerery point are equal to the sorcerer's Constitution modifier.

While the ravens are available the sorcerer gain the following benefits:

• Shared vision and hearing from all the raven's points of view in a segmented of multi-vision with the sorcerer vision main sight in the center. The Sorcerer can close their eyes and focus on each individual ravens vision.
• The collective Raven's total Constitution can maintain one concentration spell of the sorcerers. For concentration and ritual spells that are more than 1 minute, the ravens can reduce the spells time by 1 minute per raven that is currently summoned. 
• The sorcerer can transfer damage received to the ravens if the total damage exceeds the total HP of the number of ravens summoned the ravens to disappear suddenly and if all of them are gone they can't be summoned again after a short rest and the leftover damage the sorcerer takes from the hit. If the Ravens are holding a concentration spell and take damage the roll is at a disadvantage to maintain the spell.

Elemental Transmogrify Raven

The Sorcerer can target their one murder or multiple murder of ravens flocks with their own magical spell transforming them into the element that the ravens are hit with dealing that spells damage one time. Once the raven is transformed its normal damage is that element when attacking, on critical hit the raven can cast the spell that was used on it at the spell base level.

The sorcerer can choose to reverser transmogrify an elemental raven(s) and receive a sorcery point back per elemental raven. This can only be done once every short or long rest.

Shrike Ravens

The Sorcer has mastered their connections to their Ravens empowering them farther calling them Shrike Ravens as the gain following benefits.

• The Raven's damage is naturally doubled and is considered magical
• The Raven's Critical is improved from 20 to 18.
• Ravens have Advantage on all wisdom checks and saving throws.
• The Sorcer can reverse transmogrify these Shrike Ravens to receive back one sorcery point or spell slot equal to the number of ravens extracted once per long rest. 

Strike Ravens look different from normal ones their size is larger, their beaks are golden with accented silver-tipped feathers that mirror the aura of their Sorcerer master.
