PS3 / Dragon Age: Can I heal members outside my party?

Solution 1:

The answer to this is unfortunately: nope, not on PS3. You can heal "neutrals" in the PC version but not the console version. Even large area healing spells like Group Heal will fail to affect neutrals.

Depending on your party makeup you can consider using some of the "battle control" skills such as Threaten and Disengage to keep neutrals alive. If your warrior is the most threatening character in the battle he/she will draw attention away from everyone else, including the neutrals. Provided you can keep the warrior alive under this kind of fire, you will probably notice the neutrals lasting longer.
