Alex's Caves FAQ

Craft a Biome Treat and feed it to a mob or use it to locate a cave biome, then dig down toward the biome it points you to. Bring basic caving gear plus a light source, since these biomes are dark and often hazardous.

Use a Biome Treat, which points you toward the nearest Alex's Caves biome when used. You can also just explore deep underground, since these biomes generate as large cave systems below the surface.

Amber is found in the Primordial Caves biome and drops from amber-bearing blocks and Amber Monoliths. It's used for crafting and for Amber Curiosity items, so mine any amber you spot.

Place the Abyssal Altar and offer it the correct items to trigger a summoning or transformation. Check the wiki's processes section for the exact offering, since it varies by what you're trying to obtain.

Neodymium is obtained from Neodymium Nodes and related blocks in the Magnetic Caves biome. It's used to craft Neodymium gear and magnetic tools, so mine nodes when you find them.

The Magnetic Caves biome has strong magnetic fields that affect metal items and certain mobs. Avoid carrying loose metal gear or use non-magnetic alternatives while exploring there.

Diving into a biome without light, food, or a way back out, since many biomes are dark and maze-like. Also, don't ignore the unique hazards like Acid, Radrock, or magnetic fields, as they can kill you quickly.
