So this is a challenge that I first discovered from Woox when he did it on OSRS. The idea is that you let the Nibblers kill off the pillars in the first 3 waves and you finish the inferno without them. Since I discovered it, I've done multiple attempts. I even completed it once. However, when I completed it I didn't feel accomplished because I mostly used Ice Barrage to control the spawns which means the only reason I made it through was lucky RNG that I didn't get combo'd out before I was able to freeze.
That being said, I decided to not bring Ice Barrage (Staff of Light in place of a Kodai Wand). It took me a few attempts but I finally completed it.
Don't judge my garbage video editing pls ty
