Locate the Green Minion lair Overlord Guide

Welcome to Viridian Caverns. Trust your green fellows and follow them as they guide you (#1). Kill the cave creatures to collect green life force - you'll be able to call greens soon! Stay away from the poisonous plants and clouds of deadly gas. Break the barrier and keep walking. When you're in the room with a big block in the middle (#2), turn right.

Carefully guide your minions down the creeper to move the stone and make a bridge. Come back and walk to the other side across the new bridge (#1). Keep following greens for a little while until they enter a corridor filled with poisonous gas (#2). Wait until they clear the passage and continue further in. Kill some bugs and collect the green lights as you go, and remember to stay out of the green clouds! Break the barrier in your way and use the spawning pit and the blood pit behind it if you need.

Enter the passage on the right from the pit - you'll see a block. Send 5 minions to move it (#1) to make a bridge like the one before. Turn right before the archway (#2) to access it - just break the barrier and watch out for the poison in your way. Yay! So you've made it to the Green Minion Hive!

Now be a kind master and invite your new servants over to your place. Let greens take care of the environment first - cut the creepers around the hive (#1) and carry it to the nearest teleport. Follow them all the time and send a few each time you see a cloud of green. Kill some bugs in your way and neutralize the deadly gases. After a while you'll see a troll (#2). Send a few green minions to it and some others to turn the wheel to open the gate so you finally reach the waypoint. You'll also learn from Gnarl that if you position greens with a guardmark (Q) they'll be invisible for the enemy; the're also good in surprise attacks - that's a valuable piece of information!
