Regarding the map, I want to say that too many demons died. It would have been enough to limit it to 3 stacks of 2 demons each.
It seems you were only interested in clearing 30 archers on the 2nd week, and nothing was said about the losses. This replay is an example of a tactic, not a perfect clear.
Secondly, the Raise Dead spell is not always available in the guild.
You can find it on the map; there's also regeneration.
And even if the demon was not level 10, but, for example, level 8, it wouldn't have changed anything.
