Example - Big dragon terrorizing the city. Mission: Beat dragon. So whats the first thing you do? Yes! You go to the dragon (or near it.)
AKA *spoiler-blocked!*
Hurray for version 1.339! Comes with 4 new achievements (and the second sidequest is harder on easy[12 turns instead of 15] and normal[10 turns instead of 12])
The first one wasn't using difficulty's for the quest difficulty. You end up having to do loads.
The second one is using difficulty. Try it on Impossible...
It learns you to cling on to life (Hence the near fainting end)
As a result, you might make a epic move that saves your life in battle (opposed to just dying)
