The next time you hit with a melee weapon attack during this spell’s duration, your weapon turns into a darker shade, and the attack deals an extra 2d6 poison damage. Additionally, if the target is a creature, it must succeed on a Constitution saving throw or be affected by one of the following effects of your choice until the end of your next turn, as a small cloud of black insects start swirling around it.

Despair. The target is immobilized by indecision. Its movement speed becomes 0, and it can't benefit from any bonus to its speed.

Fury. The target is filled with anger. It must take the Attack action on its turn, if possible, but may otherwise act and move normally.

Hunger. The target is weakened by hunger. It has disadvantage on Constitution checks and Constitution saving throws.
