- Serpents, Mummies, Shadow Brutes, Shadow Shamans, and Wilderness Golems can drop Prismatic Shards.
- Defeat Shadow Brutes and Shadow Shamans as you progress through The Mines.
- Keep an eye out for Wilderness Golems, which may spawn on your Wilderness Farm but only become helpful after reaching the bottom of The Mines.
