Legendary Heroes. Here, we have to destroy all 6 barrows in a map with a lot of high-level monsters. Guilds are limited to 1 hero each, but they start at level 11-18.

With so few heroes it's very difficult to explore the map, since they have to stop to fight each monster and often flee. So explore the map with wizard towers and destroy the barrows all at once with lightning.

Unlike a lot of quests I didn't go for barbarians. Instead I build out Krypta and Fervus in the hopes that their summons (skeletons, rocs, and charmed enemies) can help fill the gaps in hero numbers. Additionally I actually recruit elves, as 500g for a level 11-18 elf is a good deal.

The barrow placement was extremely lucky, finding all barrows while only exploring about half the map. Additionally the solari weakened 3 of 6 of the barrows, saving me extra lightning casts.

I didn't do a great job destroying the barrows, missing clicking and even accidentally alt-tabbing (the game continued to play in the background). In the end though it worked well enough, completing the quest in 20 in-game days.
