I am building an Artificer, and I'm looking at some of his powers that give bonuses to allies. For example,
Dancing Shield. Minor action, ranged 5, Target: One Ally.
You conjure a shield of metal and magic to protect the target. The target gains a +4 power bonus to AC and Reflex until the end of the encounter. As a minor action, you can move the shield to a new target within range.
Now I can only hope that I will be able to use powers like this on myself if need be.
