Auto Axpert

 is a perk added to Fallout 3 in the The Pitt add-on.

As the description states, this perk boosts the Lone Wanderer's damage by 25% when using the Auto Axe or one of its variants (Steel Saw, The Mauler, Man Opener).

This perk is automatically added to your list of perks as soon as you collect your tenth Steel Ingot.
