The reason why for a zulrah drop buff, the avarage unique on osrs for a zulrah item is 1/-200-300 - On Runex 1/500-1500 it's retarded yes the droptable says 1:300 but it's so much more rare and i feel it's more terrible then osrs tbf
There's people with over 1-2K kills and still haven't gotten any unique.
