Your mission is to destroy all heroes. It is another of those timed levels where you must wait an amount of time before the lord of the land shows up (here 900 seconds). This time you have access to boulder traps and it is the fastest way to kill the heroes. I sell everything to build workshops and prevent warlocks and bile demons from coming. Incompressible time is 900 sec (15:00)

1:13 yes this door is locked despite not having a spinning key. 2:12 in this level I won't dig gold but use only those left by the heroes 2:45 I don't know how it happened, I was as surprised as you. For those who don't see what's wrong, I selected the bottom of the map but ended at the top of it. 2:57 slapped the reaper by mistake while dropping gold 3:01 giving gold to the reaper so he doesn't get too mad (you know what a psycho reaper is capable of, do you?) 4:24 I should've killed the troll for stealing my gold 6:24 a lvl 9 horned reaper is better then a lvl 10 because his speed spell doesn't wear off before he can cast another one, making him non stop speeded. 11:09 I must wait for some heroes before laying down traps for the knight 13:01 lvl 4 troll have the speed spell and thus are very efficient at workshop. They are idling in the lair because "YOUR WORKSHOP IS NOT BIG ENOUGH" (this sentence made me quite nervous as you have seen) 14:18 traps are a little buggy and you can end up with workshops full of traps without being able to lay them. 15:00 some explanations are needed, first 2 witches are coming on the bottom and got crushed by some of the 16 boulders then the knight party is coming and got killed by the 8 boulder traps. No more heroes left, I won.
