WHERE & HOW TO FARM

Where to farm

Alchemical Laboratory Survival or Pure Strategy in original Dungeon Defenders, unlocked by its Campaign clear.

Alchemical Laboratory is a listed Pure Strategy pet farm for the Baby Demon Lord. Treat it as a specific reward-milestone run rather than a general pet farm: clear that map’s Campaign, inspect its reward listing, and reach the listed wave. The reward milestones differ by map, so plan from Alchemical Laboratory’s own information. Pure Strategy removes hero attacks during combat, leaving the defense build responsible for the full wave sequence.

GET STARTED

How to farm

Before you go

Complete Alchemical Laboratory Campaign to unlock Survival and Pure Strategy.
Check the map reward listing for the Baby Demon Lord milestone.
Start at least two waves before the qualifying pet wave, which must be wave 15 or later.

Select Alchemical Laboratory and choose Survival or Pure Strategy.
Review the map’s reward information and identify the Baby Demon Lord milestone.
Set a difficulty your defenses can hold through the target wave.
Place defenses to cover the lanes and protect crystals during the build phase.
Start waves and watch for weak coverage; repair between rounds before advancing.
Complete the qualifying pet wave and open its reward chest.
Inspect the Baby Demon Lord’s stats and keep it or repeat the map for another roll.

Farming tips

Pure Strategy disables hero attacks during combat, so prioritize defense coverage over hero damage.
Confirm the milestone in the selected mode before you commit to a long run.

Repeat, collect and use

Repeatable for additional pet rolls, but each attempt requires reaching the map’s qualifying reward wave; pet stats vary.

Common mistakes

Using another map’s reward threshold: verify Alchemical Laboratory’s listing.
Starting too close to the milestone: begin at least two waves beforehand.
Treating a pet as guaranteed from any Survival wave: complete the specific reward milestone.

When to stop or switch

Stop once you have a usable pet or when your defense cannot reach the milestone reliably; improve the setup before another attempt.
