Deeds
A musket master swaps a pair of deeds for the following.
At 1st level, as long as a musket master has at least 1 grit point, she can take a move-equivalent action to increase the accuracy of a two-handed firearm. When she does, she increases the range increment of the firearm she is firing by 10 feet. This stacks with other abilities that increase her range increment. This deed replaces the gunslinger's dodge deed.
Fast Musket
At 3rd level, as long as the musket master has 1 grit point, she can reload any two-handed firearm as if it were a one-handed firearm. This deed replaces the utility shot deed.
