Let Go Of Me 「True Dweomer」

9th-level Transmutation (Sorcerer, Wizard)

• Casting Time: 1 reaction, which you can take even if you are Grappled, Restrained, or otherwise unable to use somatic or verbal components
• Range: Touch
• Components: None
• Duration: Instantaneous

You unleash a sudden, violent spasm of kinetic and cellular tearing directed entirely at a creature that is currently grappling or restraining you. The target must make a Constitution saving throw. On a failure, the target takes 110 (20d6) force damage as its flesh is physically repelled and ripped apart, and it must immediately release its hold on you. When released, you are instantly repelled into an unoccupied space of your choice exactly 5 feet away from the target. On a success, the target takes half damage and is not forced to release you.

Additionally, you must succeed on a DC 40 Intelligence (Arcana) check to channel the volatile physical repulsion and anchor the kinetic release. On a failure, the spell automatically fails, you suffer backlash taking 55 (10d6) psychic damage, your position does not change, and you gain no benefits.

True Dweomer. Magic of high power automatically fails the very first time you cast this type of spell, requiring you to expend twice the amount of resources (in this case, your physical fortitude) to effectively complete this magic of high power at least once. In doing so, and successfully casting a true dweomer spell, you attract instant cosmic scrutiny. The severe metaphysical friction of shaping this forbidden magic weakens your form. After casting this spell, each time you cast a spell until you finish a Long Rest, you take 1d10 necrotic damage per level of that spell. This damage ignores resistance and immunity. Furthermore, your Constitution score becomes 3 for 2d4 days while simultaneously your Intelligence score becomes 3 for one month. For each day you spend resting and doing nothing more than light activity, your remaining recovery time for your Constitution score decreases by 2 days. Finally, there is a 33 percent chance that you are unable to cast Let Go Of Me ever again.
