The Marcher is pretty diverse, he can learn from 12 different skillsets. He learns one at the beginning, and can pick up a second one when he reaches level 8.

Whenever he levels up he gets three points to spend. He can either learn a new ability or put the points into an ability that he already knows.

Don't worry about putting points in the wrong ability. You can easily pull the points off of an ability and use them on something else.
