Finally made it to 90 Firemaking and will be making a Loot from 90-99 Firemaking at wintertodt (either video or just pictures) in 2-3 weeks when I get 99. This means i wont be opening any Supply crates that i get in this time which will be about 275, I hope i have enough bank space for all those :P. My Guess it that at the current loot table i'll get around 15-20m profit.
