@Wirehall - When I get something truly workable I'll post it. I think a truly workable RPG system transferrable to a roguelike is a major design hurdle. I'm currently working on a cohesive system of powers with DiabloIII's system in mind. But of course you don't have to pick a certain Archetype, you can build your own, but Archetypes will be available to choose so you can jump in quickly.
City of Heroes has great archetype examples. And yes, for flavor the 'energy' system can be anything from 'focus' to 'rage' to 'solar power' to 'chi' to 'baddassery' to 'spinach' etc...your 'origin' category can effect this.
An example of the system I am trying to create. The 'blast' or 'ranged' or 'shoot' power is going to be fairly common. Examples...
<Flavor Text> SHOOT (RANK, EFFECTS, DRAWBACK)
The flavor text can by like Eye Beam, Gun, Ninja Stars or whatever. SHOOT is the generic game mechanic. Rank will be the damage level of the power, 1 for a sling shot and 9 for a huge cannon.
EFFECTS are status effects. Like pushback, damage over time, freeze, stun, debuff etc...explosion on target might be an effect too for like grenades and fireballs and such.
Note the EFFECTS are sort of like the runes system in Diablo III, allowing you to mod each ability somewhat.
Other generic powers:
DEFENSE [for armor, dodge or whatever helps a character avoid damage, permanent or toggle]
MOVEMENT [flying, web slinging, long jumping can all be done generically as 'terrain ignore abilities']
FIGHT [Close combat ability, bump attack basically. Rank 9 for adamantium claws.]
BUFF [Temporary + defense, fight, etc...think Hulking up, etc...]
RESIST [ignore some type of damage or status effect, a high rank is nigh immune to a damage type]
STEALTH [pretty basic, it just applies the 'hidden' status on the player while active]
Of course there will be more rare and exotic ones, like Rogue's powers, but just those ones above you can make passable versions of many heroes. Then you can build from there.
Check out HiLo Heroes online, it does some good generic treatments and solid mechanics.

PM me if you want a copy of the PDF, but if I were you I'd totally just buy it, along with the second super powers book which has tons of other 'origins' like super soldier, eugenics, side kicks, etc...
