Poison is a situational but effective Materia whenever you encounter enemies that are vulnerable to it. When cast, you'll deal non-elemental damage followed by inflicting Poison if possible, ticking down the enemy's HP over time. This is especially useful against Hell House and Type-0 Behemoth. Do beware however that like all status inflicting spells, there are diminishing returns after the fourth cast.
