Hammer formation is an encounter power available to warlords at 1st level.

CharOp Evaluation: Average [Charop Warlord]

The downside of this power is it forces a ranged Warlord to use a Heavy Thrown Weapon to use, which is hardly an optimal choice. The upside is that it's a fairly good team buff, especially if you're a Resourceful Warlord. Definitely good considering if you're interested in making a Heavy Thrown ranged Warlord for some reason.
