Path of Insanity

The voices are always there telling you to just rip apart those that appose you, limb from limb. Well why don't you listen to them what's the worst that can happen?

Mad Rage

Starting when you choose this path at 3rd level, you can temporarily boost the effects of your rage in exchange for taking a level of short-term, long term, or indefinite madness after your rage ends. While using Mad Rage your rage cannot end for its duration whether you don’t attack, are knocked unconscious, or use a bonus action to stop raging. While using Mad Rage you also have disadvantage on intelligence and wisdom saving throws. You cannot use Mad Rage again till you have been cured of your madness.

Short-Term Madness: The duration of your rage is increased by 2 minutes and your damage bonus is increased by 2.

Long-Term Madness: The duration or your rage is increased by 4 minutes, your damage bonus is increased by 4, and you cannot be charmed or frightened.

Indefinite Madness: The duration of your rage is increased by 9 minutes, your damage bonus is increased by 8, you are immune to all status effects, and your AC is increased by 4

Frightening Presence

Starting at 6th level whenever you enter a rage all creatures who see you must make a wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be frightened. If they roll less than 5 they gain a level of short-term madness on top of being frightened, if they roll a 1 they get a level of long-term madness instead.

Strength of the Insane

Starting at 10th level while you are afflicted with madness you gain the following stat bonuses depending on your level of madness. These stat bonuses can make you exceed 20.

Short-Term Madness: +1 Strength, -1 Intelligence
