Another vote for the strength of second wind as a minor. Especially in combination with Cloak of the Walking Wounded.
And in concert with battleforged armor to add bonus d10s onto the healing party.
A dwarven defender with the above pairing of items can easily jump from very bloodied to full hp as a minor action without outside assistance, freeing up the party leader to worry about healing someone else.
Every Encounter -- because both Battleforged Armor and Cloak of the Walking Wounded grant their extra healing if bloodied as a Property, not a Daily power.
What are those items and what do they do?
I ask because the other Dwarf players have been utterly slacking in letting the DM know about what kind of items would work for their PCs...so we're running rather item-poor.
(If you can, use book references, since I don't have DDI.)
