Evoke Energy (Wizard)

Drawing Upon the Raw Magical energy one can access, you coat yourself in it, covering your body, threatening to destroy you, before releasing it all outwards in a powerful blast. Note: (This spell has different versions, depending on which spell-casting class is using it, with options which change based on what class/sub-class/magic type you use.) For Wizards, the spell functions as follows: 

All creatures within range, excluding you and any with full cover, must make a dexterity saving throw taking damage equal to 4d10 + your spell casting modifier on a failed save, or half as much on a success. Choose a damage type, or option from the options below. The spell gains different additional effects depending on the damage the type you choose: 

Force: The damage type is Force, and magical Barriers (Such as frozen parts of a wall of water, or sections of a wall of stone,) within range, also take the damage. 

Acid: The damage type is Acid, and non-Magical Objects, and Barriers made of Stone, Metal, or other inorganic materials within range take the damage as well. 

Cold: The damage type is Cold, and any section of water within range freezes in ice. Creatures that would be trapped in the ice created by this spell are pushed to a location where they won't be trapped, as determined by the DM.

Fire: The damage type is Fire, and flammable objects not being held, or carried within range are set on fire.

Lightning: The damage type is lightning, and creatures in metal armor have disadvantage on the saving throw.

Poison: The damage type is poison, and small or smaller creatures have disadvantage on the saving throw.

Psychic: The damage type is psychic, and the wave of energy is harder to sense by being with drastically different minds, Abberations, and Oozes disadvantage on the saving throw.

Thunder: The damage type is thunder, and constructs within have disadvantage on the saving throw.

Necrotic: The damage type is Necrotic, and this spell counts as a spell of the school of necromancy for any feature that effects Necromancy spells.
