Path of the Insane

Your rage has changed into a state of insanity that makes you a crazy foe to fight.

Mad Man

When you take this subclass at 3rd level you are considered insane. This has no effect on gameplay, aside from raging. Scrying will reveal your insanity. You gain a new stat called insanity. Insanity starts at 10 + int modifier.

Temporary Insanity

Starting at 3rd level your rages are swapped for insanity. You cannot cast, or concentrate on, spells while insanity is active. When insanity is active you get a bonus to constitution saving throws from the Insanity table. While insanity is active your insanity score goes up by 4.

Crazed Frenzy

Starting at 6th level, while raging, you can attack using a bonus action. Doing so gives you your damage bonus, but negative, for the attack roll.

Mad Speed

Starting at 10th level, while insanity is active, you can move past your base speed. For every 5 ft you move past your base you get -1 to attack rolls, and +1 to damage. If you move more than 15 ft you have to make a constitution saving throw. The DC for this saving throw is 13; for every 5ft you move past 15ft the DC increases by 2. Once the DC is equal to or greater than 30 you cannot use this ability until your next turn.

Erratic Fighting

Starting at 14th level, when making an attack roll, you can use 5ft of movement to add a +1 bonus to your attack. While raging you can you this up to 8 times. So 10ft movement lost, but a +2 bonus to the attack roll. At 8 times you lose 40ft of movement.
