Crossbow Training (Ex)
Replaces: Gun Training
Starting at 5th level, a bolt ace can select one specific type of crossbow, such as hand crossbow or heavy crossbow. She gains a bonus on damage rolls equal to her Dexterity modifier with that crossbow. Furthermore, when she scores a critical hit with that type of crossbow, her critical modifier increases by 1 ( 2 becomes 3, for example).
Every 4 levels thereafter, she can pick a different type of crossbow, gaining the bonus damage and increased critical multiplier with that type of crossbow as well. This ability replaces gun training. Archetypes 2
