Use Magic Item is a second level artificer utility power introduced in Eberron Player's Guide.
Because of the change in magic item rules, this power is completely useless. Originally, characters could only use 1 daily magic item power per tier and an additional use on each milestone, before an update allowed unlimited use of items.
