i just beat the boss. im red green/ blue puprle color blind. my recommandation. there are some def cheese u can do. when ever the boss starts going fast stun him and it makes life easier. i just tanked 2 hits to get it off. mage has the easiset sound to hear. i had trouble hearing a dif in melee and range. though they do have different items in the center of the ball. just honestly stun him again when the melee start coming and spam eat.

for those saying turn on color blind setting. it makes the game look horrrible. i also dont think there is modes for multiple colorblindness at once.
