Heal says (Light Side Force User Only). Does that mean you must have a light side morality (Above 70)? This seems like a pretty serious restriction on the power.

My understanding of this:

Players start as Light Side Users (LS), when you hit 29 morality you become a Dark Side User (DS).

Then a DS user needs to hit 70 morality to get back to being a LS user.

70 morality and above is LS paragon and required to affect destiny pool, the moment you drop back down you are still LS user but don't change the destiny pool.

So as long as you use LS pips normally you can heal. It's once you fall to the dark side that you can't.

Well Dark Side can heal by hurting people.

Heal says (Light Side Force User Only). Does that mean you must have a light side morality (Above 70)? This seems like a pretty serious restriction on the power.

Morality 1 to 29: Dark Side Force User (once here, you are considered a DS User until you have 71+ Morality)

Morality 30 to 70: Light Side Force User

Morality 71 to 100: Light Side Paragon

Dark Side Force Users cannot use Heal, but they can learn Control upgrades which allow them to restore their health by hurting others.

[edit]

Numbers fixed.

Morality 1 to 29: Dark Side Force User

Morality 30 to 50: Light Side Force User

Morality 51 to 100: Light Side Paragon

This is slightly incorrect. Once a dark side Force user dips below 30, he or she must raise their morality above 70 before the are considered a light side Force user again.

Yes, I know. That's what happens when you type fast when at work. I also put "30 to 50" rather than "30 to 70". I'll fix it.

Everyone posting is correct. It's found on page 52 F&D, "[Player Characters] remain light side users until their Morality drops beneath the dark side threshold."
