Not sure if the bonus of the scoundrel is a penalty???
Reduces the requirement of gold by 1 turn actually makes it harder... the 2 turn requirement of the stage that is in reference by asgar will be reduced to 1 turn which makes it impossible because there's 2 enemies.
Eventually when u get enough gear u can 1 shot enemies easily, but regardless of how much damage u can do you still need 2 turns to kill 2 enemies.
It must be an oversight by the author. They probably meant to increase the turn limit and not "reduce" just because when u reduce something doesn't mean it's a bonus hah. But if it is supposed to be a penalty, then the stage needs to be 3 turns for gold.
