Whenever any mob or player is hit with the radiance beam, it makes them immune to all damage and making them invincible, I had found this out when I was messing around with Electroblob Wizardry and this Addon and he had hit me with it making me immune to damage for an undisclosed reason. After further testing I had found out that for some reason it would only work if the player was in survival mode. Not working in creative for who knows why.
