I could swear I found a feat that gave +2 Heal and allowed me to trigger somone's Second Wind as a Minor Action. Could someone tell me what this is 'cause I am going crazy trying to remember this.
It's stabilize, not activate second wind, as a minor (which would effectively give n-1 extra minor action heals per encounter, where n=number of party members).
There is a Skill Power that allows you to trigger another person's SW with a minor. I believe it is a level 6 Encounter power, and if you don't want to give up your regular L6 utility, can buy it with the Skill Power feat. No +2 to Heal checks though.
