Smiter

From Guild Wars Wiki

A smiter is a character who uses skills from the Smiting Prayers skill line from the monk profession. Smiters are often monks, as they can increase the power of these skills using runes, but other professions, in particular Elementalists and Mesmers have been known to use a skill bar based predominantly on smiting prayers.
