Mana Void

5th-level evocation

• Casting Time: 1 reaction, which you take immediately after you see a creature within 90 feet of you cast a spell
• Range: 90 feet
• Components: S
• Duration: Instantaneous

You take advantage of the negative space of energy left in the wake of casting a spell. The creature that cast the spell is immediately struck by a backlash of destructive force, dealing 2d10 force damage plus 1d10 force damage per level of the spell that creature cast. If the damage from this spell requires the creature to make a Constitution saving throw to maintain concentration on a spell, they have disadvantage.

Winter's Curse

7th-level enchantment

• Casting Time: 1 action
• Range: 90 feet
• Components: V, S
• Duration: 1 round

You point at a creature that you can see within range and force it to make a Charisma saving throw against your spell save DC. On a failure, the target is restrained by icy bands until the end of its next turn as the curse of winter descends upon them. On a success, the spell ends.

Every creature of your choice within a 30-foot radius of the target must make a Wisdom saving throw against your spell save DC. On a failed save, the creature is overcome with maddening hatred of the target and must use it's next turn attempting to kill the target as if their life depended on it.

The spell ends if you or your companions harm the target. A creature affected by this spell can repeat the saving throw with advantage if it is harmed by you or your allies.

Classes: Bard, Sorcerer, Warlock, Wizard
