With the Foundations, you can buy as many as you want for different effects. One of my examples was building Fulcrum Shift, the Kinetics power: it had one Ranged AoE External Foundation for the Damage De-Buff for your enemies, then one AoE Personal Foundation for the Damage Buff for your allies.

So, for your Strength of the Elders it would be:
Personal(Heal + Regeneration Rate) + External Cone(Energy Damage + Disorient)

Which makes it a Heal and Regen boost affecting only yourself, and a cone of Energy Damage (which electricity attacks deal) and Disorient. Which is, I believe, what you were going for.

See? Flexible.

Oh, and Leonin, no thanks. I leave the balancing of the points system to someone more knowledgeable of game balance than myself. It's why I made my Attributes descriptions so vague. =P

Seems reasonable, but I'm not so sure about your take on things like Range and Magnitude. The system I was trying to make with Types instead of Delivery Systems is one that's (A) incremental and (B) flexible. Why should we stop at 240 ft? What if I want my AR/Dev's Signature Power to be a staggeringly-long range sniper shot from half the map away? That would be quite a signature. The point of Signature Powers is to be able to make anything imaginable with the current system, and players will almost always tend toward the superlative when creating something "signature".

Not bad, but a little too inflexible.

Edit: Oh, and thanks for reminding me, I forgot to add Flight and Teleport. Excuse me while I edit my own.

Signature Powers:

Foundation: Signature Powers can have Foundations onto which Attributes can be added. Foundations can be Personal, affecting only you, or External, affecting others. Signature Powers get their first Foundation free.

Personal (1)- The Attribute only affects you, or for Area of Effect Foundations, a short distance around yourself.
External (1)- The Attribute affects your current target, or for Area of Effect or Cone Foundations, a short distance around your target.

Range of Effect: Signature Powers can have their Foundations have a Range of Effect.

Range (1)- Makes the Signature Power a Ranged power, adding range per point spent. If no points are spent in Range, the Foundation's Attributes affect only melee range.
