MHP3rd didn't have dragonblight at all it was removed, idk why though.

But Deviljho does have dragonblight in MH3/Tri which came before MHP3rd and MH3U which came after MHP3rd

Also note that in Tri Dragonblight reduced Affinity and not element but from MH3U and onward it now removes any status/elemnt your weapon has.
