Let's see... This is where I come in, since I've been playing a stat-based game recently(Same one as when we were thinking up new stuff for R3. =P)...
Dexterity: Dexterity represents your character’s reflexes, aim, and agility. Add your Dexterity score to damage for ranged attacks, such as those from phasers or disruptors, as well as to Dexterity-related skill checks (such as dodging debris from an exploding console or piloting a starfighter). In addition, for every 5 Dexterity points you gain, you will _____.
No clue for this. I'd say speed, but that should be part of the main abilities... =/
Mind: Mind represents your character’s mental prowess; their intelligence, wisdom, and charisma. Your Mind score applies to damage caused by certain types of species-based attacks (i.e. aggressive uses of telepathy), as well as to Mind-related skill checks (such as diagnosing an alien disease, programming a computer to repair complex machinery, or plotting a ship’s navigational course). In addition, for every 5 Mind points you gain, you will ______.
Going off strength's HP boost, this should be Mana or something similar; however, I have no clue what you're planning for that. =P
Also, just curious, for the Redeemed Borg, we go off their base species, right? So, say, we'd start with human if we're like Kaze, right? Jut checking.
