well all depend on luck because "example" Cure/paralysis is 1/8 in (Hide mob >:3 ) is statistical that means in 8 mobs is posible 1 drops the item but every fight u cant fight 8 rare mobs and not is a count accurate and can kill 500 mobs rares and u can got 1 Cure/paralysis, HP mat or sooo Dex mat. for my part is only luck i got one time Phyco Wand killing 56 "Mil lily" and drops say 1/1032 all depend on luck but if u see more rares mobs try kill many more for my the table is good and estable
