Cruciatus Curse

The user speaks the invocation 'Crucio' and points their wand at 1 living being within 25ft, the target must succeed in a DC 26 Dexterity saving throw or be affected by the curse.

If the target fails the saving throw they become affected by the curse - they are fully prone and paralyzed, each turn the victim must succeed in a DC 20 CON saving throw and a DC 18 WIS saving throw or take Nd4+6 of a damage type they are not resistant/immune to, if the victim succeeds in both saving throws they will take half damage, for every turn the curse is affecting the same being the DC of the WIS saving throw is increased by 2 and the DC of the CON saving throw is increased by 1.

N is decided by this method: the user rolls a d4 until he surpasses his proficiency bonus, the number of times the user rolled a d4 is then equal to N, for example: if the user's proficiency bonus is 5 and they rolled 1, 3, 2 the user rolled a d4 3 times before surpassing their proficiency bonus, which means N is equal to 3 and the victim will take 3d4+6 damage in that turn.

The user may dispel the curse as a bonus action, as long as the user is pointing the wand at the victim and is concentrating, the curse endures, the curse automatically ends if the user moves outside 25ft of the victim or loses sight of the victim.

(yes, the 'torture curse' using the d4 is intentional)
