Expert Strategy Guide

Pro Tip

All monster drops! Slime (Green Slimes floor 1-39), Bat Wing (Bats floor 30-50), Solar Essence (Ghosts/Squid Kids 80+), Void Essence (Shadow monsters 80+).

Strategy Analysis

99 Slime is lots of green slime kills. 10 Bat Wings easy. Solar/Void from deeper floors need combat preparation.

Year 1 Completion Guide

Farm early floors for Slime/Bat Wing. Deeper exploration Summer/Fall for Essence when you have better weapons.

Common Mistakes to Avoid

Underestimating 99 Slime requirement. That's 50+ slime kills. Also: Shadow monsters hit hard, bring food.

Why This Reward Matters

Small Magnet Ring increases pickup radius. Stacks with other magnet effects. Helpful for mining.

Alternative Sources

Krobus sells Void Essence (Monday). Solar Essence rarer but occasionally on Traveling Cart.
