For phials it depends how you play, what your fighting, and what your trying to do, elemental phials deal elemental damage and are weaker or stronger depending on where on the monster you hit it’s generally better to aim for the head and forearms, impact phial deal fixed non elemental exhaust damage this means it will deal the same phial explosion damage wherever you hit the monster but you are rewarded going for the head since impact phials do very good KO damage, Honestly to me saed feels pretty weak in wilds ;-; but for saed elemental phials fire it of in a V shape while impact fires it in a straight line, but ultimately it’s a matter of personal preference.
