OK, this one has been driving me nuts. Along with an attack trick, bow supremacy allows you to add spike to any bow.
What advantage does this give?
All I can find on the spike quality is that I can use the item as a melee weapon if I have the edge proficiency.
Am I missing something, or is the final capstone for one of the ranged attacks is that I can now physically beat people up with my bow if they get too close vs just shooting them?
Well, you get the trick (which is butch as &$%#!)...
To get an understanding of how the feats are structured, you get a small perk and a trick or stance for almost all weapon feats. In practice, this is often that it gains a simple customisation (ex. Axe's gain Hurl
) or that it can be used as a different weapon type. Then you get the trick - in Bow Supremacy it's the 3 arrow shot, which is butch.
From a thematic perspective, it's like how Legolas stabs a heap of Orcs with his arrows in hand to hand combat in Lord of the Rings.
