Do not dare use the button so advanced in game...

An addition: add map configuration saving, or, place back the same setup you had the last time you played the scenario. For leveling grinding it is essential. I am capturing the scenario in a picture but it is still heavy chore to re-place all figures on the board and you still have to add boosts dynamically. I managed to win an as-yet-few-figures-scenario with only two figures. Hard core? _I_ would add a scripting language to program sets of configurations and placement rules and to calculate optimum coverage configurations then batch the battles, like a movie, but it is only what I would do.

The "Reset pts" button moves all the points that have been assigned to that party member's skills back into the "skill points available" to redistribute to other skills as you please. Essentially it resets the party member as if you had never spent any of their skill points while remaining at the same experience level (for a fee, paid in scrap).

It's actually really useful for new players (like me). You can spend skill points on whatever you like and not worry too much about whether it's the right "build" to maximize damage, because you can always change your mind later.
