When facing the Black Diablos in MH Stories, it's crucial to be well - equipped. You should have a weapon with good reach to keep your distance from its powerful close - range attacks. Try to stay on its sides or behind it as much as possible, because its frontal attacks are the most dangerous. Pay attention to its movements. For example, when it rears up, it's about to do a powerful charge, so be ready to dodge. Also, use items like traps and potions effectively to gain an edge in the battle.
You should also pay attention to its attack patterns. When it rears up or starts to charge, that's a sign of a big attack coming. Dodge in time and then counterattack. Prepare different types of weapons and items. For example, a weapon with high cutting damage can be very useful. And don't forget to bring healing items to keep your character alive during the battle.
