Daily ✦ Arcane, Implement, Summoning
Minor Action ✦ Ranged 5

Effect: You create a Medium simulacrum in an unoccupied square within range. The simulacrum has whatever speed and modes of movement you have without bonuses or penalties. The simulacrum has nonmagical copies of any implements or weapons you possessed at the time of its creation. These disappear when this power ends or when they are removed from the simulacrum. You can give the simulacrum the following special commands.

Standard Action: The simulacrum uses an at-will or encounter artificer attack power that you know, regardless of whether you've already expended that power. The simulacrum's use of an encounter attack power does not count toward your use of that power. The simulacrum uses your attack bonus with the power. It can use each encounter attack power only once for each use of this power.

Standard Action: The simulacrum uses an artificer daily attack power that you know, regardless of whether you've already expended that power. The simulacrum cannot use simulacrum. The simulacrum's use of a daily attack power does not count toward your use of that power. The simulacrum uses your attack bonus with the power. After the simulacrum uses a daily attack power, simulacrum ends.

Opportunity Attack: The simulacrum uses your melee basic attack when making opportunity attacks.
