An
epic marksman is an experienced
marksman. The epic marksman is an ultimate master of firearms. He can shoot an apple's stem at 3,000 paces, fire rifle shots in rapid staccato, and perform selective surgery at range. Those who anger him drop dead in the streets. Ranged combat with firearms is his specialty, so he keeps improving it. Increases to speed and mobility can help him avoid melee so he can do what he does best. He grants ability increases to dexterity. If he is determined to put an ability increase elsewhere, he is told to soak his face in ice water until he feels better.
