Hillside Cavern Guide: Pals, Bosses, and Loot

Updated 2026-07-22

Hillside Cavern is the grassland starter dungeon — the one you'll stumble into first, tuned for level 5–10. Runs are quick, the danger is low, and the payoff is real: early spheres, a Copper Key, and a boss room whose winner might become the strongest Pal on your team for the next ten levels. Every cavern rotates its entrance spots, so check the List of All Dungeons for what else is out there.

Why Run It Early

Two things make this cavern worth detouring for before level 10. First, chests: Mega Spheres this early trivialize catches that would take five Pal Spheres otherwise, and the Copper Key opens the locked chests you've probably been walking past. Second, the boss room — an oversized boss Pal at level 10–13 that, once caught, outclasses nearly anything wild at this stage.

The Pals in the Corridors

The regular spawns are a small dark-leaning crew at level 5–10 — nothing a starter team can't handle, and Fuddler is a genuinely useful early catch for base mining. Turtacle paddles in the water pockets.

The 30-Pal Boss Pool

Hillside Cavern has the widest boss lottery of any cavern — 30 possible bosses, one rolled per run at level 10–13. Standouts worth re-running for: Eikthyrdeer (your first proper mount), Direhowl (a fast, cheap ride), and Dinossom (a sturdy grass bruiser). The full pool:

TipWeaken the boss and throw spheres instead of finishing it — a caught boss Pal comes at the level it fought you, which is a head start on anything you could catch outside at this point.
