The reward is about 10 gold. Also the subdungeon provides a lot of dark tiles.

Upon reaching the gold, 5 zombies of the same level as you will appear in a row, blocking the exit. Noted that {{s|PISORF}} cannot help you to escape because the zombies are side by side, and that zombies are not easy to deal with on maps with high difficulty due to the increased monster health.

It is recommended that you only take the gold when you are well prepared. The lower the level, the better chance you have to escape safely. If you find this dungeon at level 6+, not picking up the gold is recommended, because you may not be able to get out with major loss of resources or even death. 

Alternative use for the subdungeon: the dark tiles is plenty for {{s|BLUDTUPOWA}}, or just use the dark tiles as you can harvest (by not taking the gold, you can get our freely).  {{s|ENDISWAL}} can provide even more dark tiles.

Special solution: {{c|Assassin}} have the ability to instantly kil on lower level monsters. Entering just before leveling-up and pick up to gold. After killing the first zombie and level up, the rest of the zombies can be all-carrots with a single blow, providing lot of experiences.

The video provided shows a level 1 entry with {{s|WONAFYT}} and {{s|ENDISWAL}}. {{s|WEYTWUT}} is also a method to consider to escape without killing monsters.
