Cast Misty Step once per long rest

Briefly surrounded by silvery mist, you teleport up to 30 feet to an unoccupied space that you can see

 Cast Blight twice per short rest

 Necromantic energy washes over a creature of your choice that you can see within range, draining moisture and vitality from it. The target must make a Constitution saving throw. The target takes 8d8 necrotic damage on a failed save, or half as much damage on a successful one. This spell has no effect on undead or constructs.

Cast Mental Prison once per long rest

You attempt to bind a creature within an illusory cell that only it perceives. One creature you can see within range must make an Intelligence saving throw. The target succeeds automatically if it is immune to being charmed. On a successful save, the target takes 5d10 psychic damage, and the spell ends. On a failed save, the target takes 5d10 psychic damage, and you make the area immediately around the target’s space appear dangerous to it in some way. You might cause the target to perceive itself as being surrounded by fire, floating razors, or hideous maws filled with dripping teeth. Whatever form the illusion takes, the target can’t see or hear anything beyond it and is restrained for the spell’s duration. If the target is moved out of the illusion, makes a melee attack through it, or reaches any part of its body through it, the target takes 10d10 psychic damage, and the spell ends.

Cast Seeming Once per short rest

This spell allows you to change the appearance of any number of creatures that you can see within range. You give each target you choose a new, illusory appearance. An unwilling target can make a Charisma saving throw, and if it succeeds, it is unaffected by this spell.

Flap
