Writer's Block

Channeling your artistic frustrations into a physical, malleable energy, you can shape them enhanced by magic into a visible mass, taking form according to which effect you choose. Only one form can be used, and it cannot be changed during the spell's duration.

Block - You form a dome of 15 feet in diameter which shines dim light in a further 5 feet around it in every direction. It is translucent and provides half cover to all allies under the dome. As a bonus action on your term, you can choose to buff allies within the dome further, providing advantage on saves and making incoming attacks deal 75% of the damage that was rolled, rounded down for the entire round. This feature cannot be used more than once during the duration of the spell.

Argh - You form a vague semblance of a martial weapon of your choice such as a staff, sword or spear on a large scale. Regardless of form, it will deal bludgeoning damage equal to 3d6 + your spellcasting modifier on the turn that you cast it to any creature in a 10 foot semicircle 5 feet from the caster, making a swiping motion. On subsequent turns, it significantly decreases in power, dealing only 1d6 + your spellcasting modifier. However, subsequent uses during its duration consume a bonus action rather than a full action. 

If you are put under a condition which would either soothe or cripple you such as being charmed or put to sleep while either effect is active, the effect will disappear immediately. Instead, roll a d2. On a 1, the energy no longer under your control explodes violently, dealing 4d6 damage to all creatures in a 30 feet radius from the caster's body or half as much on a successful Wisdom save against your spell DC. Upon rolling a 2, the energy dissipates peacefully and instead heals allies within a 30 feet radius from the caster's body for 2d6 + your spellcasting modifier.
