While in rage form, at the end of each turn make a WIS saving throw of 10. Every subsequent success raises the DC by 3. This carries over between rages and does not reset until after a long rest.  

Upon failure, the user becomes an incarnate of wrath.

Juggernaut. The user's skin darkens and their mind becomes immersed in mindless anger. Any resistance the user has during their rage is upgraded to immunity. The user is immune to being frightened and charmed.

Boiled Blood. The user's blood involuntarily boils and begins to leave their body in the form of a burning red mist. The user cannot be healed by any source while enraged. At the end of each turn while enraged, the user takes half of their current health (rounded up) in damage. This damage cannot be prevented. Any creature that ends their turn and stars their turn within 5 feet of the user takes 2 fire damage and flammable objects may start catching fire if exposed to the user for over 10 seconds. 

Berserker. The user must make an attack at the end of each of their turn, if the only options are allies the user can attempt to resist the effect with a WIS saving throw. The DC is base on the counter. On success, the user can also choose to end the rage. On failure, the DC increases by 3 and they will attack the target as if they were their worst enemy. 

The rage only ends when either of the following conditions occur.

• The user falls unconscious. 
• The user attempts to make a WIS saving throw (DC same as their DC when entering the rage) at the end of their rage and succeeds. On failure, the DC increases by 3. 

Other effects from rage still apply.
