Witch of the swamp guide using Veteran (250 units)

This setup shows the maximum losses, and in the end my real losses. To get max you must be really unlucky.

So max loses with vet: 530R, 50C
Max losses without vet: 547R, 75C, 19M
So even in worst cases you save 17R, 25C, 19M. I say it was worth the buy.
If anyone is willing to start of a new extensive adventure topic like Sidv had please feel free to use my results.

You can even further reduce losses by ignoring the leader camps. It will cost some xp, but saves ~150 recruits and you still get all loot.

Camp 7 is not entirely correct afaik. With your current setup the 1S can die. Better to go for 100% safe 50R, 20M/S, 180C (-44R).

Other than that you have a few nice aditions that shave 1-2R of my current setup, thanks!
