This is easily the artifact that was most desired during my first Drowned City run. Everyone knows that Pathfinder is incredibly powerful - so what about a permanent Pathfinder that doesn't even have the unengaged requirement, and can move two spaces for good measure? Drag enemies around as you like, and be wherever you need to be!
Sure, the flip side is a little sad. The fight is of limited use. Finn Edwards or other Dirty Fighting users who can deal 2 damage with this. That still only puts this on par with 'okay' attacks, and most fighters have standard weapons that can be used more than once per turn for more consistent results.
But when you already have access to one of the stronger effects in the game, it doesn't matter if the 'bonus' effect is weak. The flip effect of this could not exist, and this would still see constant use - and if you happen to be on the path where you can get this on your second mission, it should be a priority objective to do so.
