EDIT: Okay, done. And with that said, I should ask: will it be possible to increase either energy capacity or energy regeneration through stat points? That'd add a couple new dimensions to stat allocation.

It says in the thread header no to that:

[quote=@Behemoth542]Both the maximum [color=yellow]Energy[/color] and its [color=gold]regeneration[/color] can be modified by [b]traits[/b], but not by StP[/quote]
You'd have to use a 'Trait' perk to alter your Energy, but can't change it with stat points. Something like 'Battery Compartment: Increase Maximum Energy by 10' or 'Draw Capacitors: As long as Energy level is above 4, regenerate 2 Energy per turn instead of 1' or something similar to that. You might even be able to get away with something like 'Energy Leech: If you get attacked by the enemy, gain 2 Energy'.

A better way would be to create a skill which is based off of other attributes, like Nightingale's ([@Genni]'s) [i]Combat Triage[/i]. She can increase the effectiveness of the ability by spending skill points on her Attack, getting more healing each time she spends the same amount of Energy.
