So I have a 6IV male ferrothorn with a good nature, and the female has a good nature but not too great IVs... is there a chance of the offspring gaining 5IVs from the male parent???
Yes, it takes IVs from both parents.
As of Pokémon X & Y, this item, when attached to a Pokémon while breeding, will cause the baby Pokémon to inherit 5 IVs from its parents
