HEALING/SUPPORT POWERS There's the whole canon line about Winry's hands being for helping people, and she does know about medicinal stuff in canon (curing injuries or at least knowing how to help with even bad injuries, helping with surgeries, being an automail mechanic requires some medical skills too... oh and she did help a woman to give birth to a baby etc. also the only child of doctors here.).
So she would be helping people with her new healing powers and possibly recharging their batteries too to support them in the fight. Mysterious with light appearing while she touches someone and then they're ready to do at least some things again – depending on how much injury there was to heal and how much of it could be healed by her. Or if someone isn't that much injured, but just almost out of energy, maybe she could also give some of her own energy to them... Meanwhile she'll try not run out of battery too fast herself, haha?
