Shine Potion

Shine Potion makes a character glow for 5 minutes, which is useful for exploring caves. It loses some of its usefulness when you obtain the Orb of Light or a Mining Helmet, as the materials needed to make the potion could be used for more useful potions. However, unlike the Orb of Light, the light source comes from the player, which will not fall behind, and unlike the Mining Helmet, you can wear a helmet with more defense.
