Flumlock's Insanity Blade

Insanity Blades are chaotic combatants who thrive in the midst of battle. They embrace the madness and the unpredictable nature of the fight, utilizing it to their advantage. Their strikes and attacks are unpredictable and often accompanied by wild and unpredictable magic effects. They use their ability to manipulate untapped magical energy to warp reality itself around them.

Madness Unleashed

Starting at 3rd level, Raw and chaotic magic begins to influence your strikes. When you score a critical hit, you can roll a d10 to determine the magical effect of your attack. Roll a d8 and consult the following Madness Table:

If the effect requires a saving throw, the DC equals 8 + your proficiency bonus + your Constitution Modifier.

On a 1- Your attack becomes coated with primordial energy filling your attack fills the target's mind with madness. The target must succeed on a Wisdom saving throw or become frightened until the end of your next turn.

On a 2- The Raw magic in the air coalesces into an illusion of yourself that copies your movements. The illusion appears behind the target and lasts until the end of your next turn, giving you advantage on your next attack against any enemy within 5 ft. of the illusion.

On a 3- When your attack hits an enemy you drain their life force. When you deal damage you regain hit points equal to half of the damage you deal.

On a 4- As you hit a target magical energy is left behind on the wound. At the start of each of the target's turns, they must succeed on a Wisdom saving throw or take 1d6 Psychic damage. On a success, this effect ends. As you level up the damage dealt becomes stronger: At level 10- 2d6 Psychic damage, At Level 18- 3d6 Psychic damage.

On a 5- As your attack strikes your target an explosion of raw arcane energy explodes from the wound. The target and all creatures within 5 ft. of the target must succeed on a Strength saving throw or be knocked back 5 ft. and take 1d6 force damage. The target immediately fails. As you level up the damage dealt becomes stronger: At level 10- 2d6 Force damage, At Level 18- 3d6 Force damage.

On a 6- When your attack meets the enemy magical energy lashes out at the target, temporarily dazing them. The target must succeed on a Wisdom saving throw or become stunned until the beginning of their next turn.

On a 7- Your attack draws in raw magic from the air bolstering your physique and speed. Until the end of your next turn your Dexterity and Strength score increase by +2.

On an 8- Your attack drains a large quantity of primordial magic from the air. Roll twice on the Madness Table, and use both outcomes. If another 8 is rolled, reroll.
