Root Abyss Boss Mechanics

I don't claim to know Unlimited changes, but just stating that any one person cannot obtain repeated equips or weapons even with 10x or 20x drop rates. They only drop the rest of the list, not repeated ones. The only possible explanation is, someone else could've gotten what you gained and stacked it all together. I denied it in the 1st part, but the 2nd part I sorted hinted at it with multiple computers, contradicting myself haha.
