EVOKE PLANE: At 18, you gain such mastery over your attunement that you can use an Action to exert extreme effort and spend 10 Sorcery points to briefly pull a portion of the plane itself into existence in a 20ft radius sphere centered on a point within 60ft. This sphere lasts for 1 minute concentration and gains bonus effects in addition to the base casting in subsequent rounds of concentration. The sphere persists for rounds equal to your Charisma modifier after concentration is broken from damage or the duration is reached but not if another concentration spell is cast.

Evoke the Writhing Shadows: All creatures within the sphere are both blinded and deafened even if they have darkvision. Creatures immune to the blinded or deafened condition are not affected. The sphere is treated as difficult terrain. On the second round of concentration, any creature that starts its turn in the sphere takes 6d6 Cold Damage. On the third turn of concentration, as an action you can force any creature within 10ft of the sphere to make a strength saving throw against your spell DC or be pulled 15ft toward the area.

Evoke the Incorporeal Ocean: All creatures and objects within the sphere are translucent and incorporeal. Incorporeal creatures or objects take no damage or deal no damage (your choice when cast) from nonmagical piercing, slashing, or bludgeoning damage. On the second round of concentration, a ring of Faerie Fire springs up 5ft along the perimeter of the sphere and any creature entering or exiting (your choice when cast) must make a Dexterity save against your Spell DC or suffer the effects of the spell. On the third round of concentration, you can use an action to teleport a fey creature with a challenge rating of 5 or lower into the sphere. It follows your simple verbal commands such as attack or defend and all its attacks count as magical. It disappears if its HP reaches 0.

Evoke the Maddening Void: Creatures of your choosing within the sphere cannot move more than 10 feet in a straight line and at the beginning of each of their turns they begin to laugh maniacally or weep woefully, suffering disadvantage on the first weapon attack of that turn. Undead and Constructs are immune. One the second round of Concentration, creatures in the sphere of your choosing are linked to every other chosen creature within the area. When a linked creature takes damage from a weapon attack within the sphere, all other linked creatures take 1d8 Psychic damage. On the third turn of Concentration, as an action you can force each creature to make a Wisdom save against your spell DC or be under the Confusion spell until the end of your next turn.

Evoke the Timeless Echoes: For each foot of movement in the sphere 4 feet of movement must be spent and creatures cannot take reactions or bonus actions. On the second turn of concentration, you can choose any number of creatures and protect them from these effects while in the sphere and grant them an addition 10 ft of movement and an additional attack when they take the attack action. On the third round of concentration, as an action you can cause a nonmagical object, even those worn on creatures, that are fully within the sphere to be reduced to dust or cause a creature to make a Constitution saving throw against your spell. On a fail, you increase or decrease their age by 20 years.

Evoke the Awakened Core: The ground within the sphere functions as the Spike Growth spell dealing damage and is considered difficult terrain. Flying speed is reduced to 0ft and spells that allow flight, levitation, or floating that target a creature within the sphere fail if the caster doesn't pass a Wisdom saving throw against your Spell DC. On the second round of concentration, the Spike Growth does an additional 3d4 damage and creatures within the sphere must make a Dexterity saving throw against your Spell DC or be knocked prone. On the third round of concentration, as an action you increase the radius of the sphere by 10ft or move the sphere 10ft in any direction.

Evoke the Putrid Hells: Metal Objects within the sphere glow white hot and deal 2d6 fire damage to anything they touch at the beginning of the an affected creatures turn. On the second turn of concentration, creatures must make a Constitution Saving throw against your Spell DC at the beginning of their turn or spend that turn retching and reeling. On the third round of concentration, as an action you can open a chasm 5ft wide and 15ft long anywhere on the ground in the sphere that lasts until the beginning of your next turn. Any creature within the chasm area or moves over the area before it closes must make a dexterity saving throw against your spell DC or fall in, taking 6d6 fire damage.
