Blind Rage

Once activated, the player is in a blind rage for the duration of 30 seconds (5 rounds of combat). While in a blind rage, the player cannot tell friend from foe and attacks the closest creature with advantage. Advantage on saving throws. Advantage on strength checks. Resistance to nonmagical weapons. Along with this feature comes 5 Berserker points, allowing the user to spend a point to perform a special action. Rage ends after the duration or once incapacitated. 

If allies and foes are within the same range of the player, DM rolls dice to see who is attacked. Dice range will change based on player and enemy count.
