Weapon Proficiency
Weapon Proficiency improves weapon damage and the impact weapons have on an enemy's structure. IGN states that it requires 500 XP. Its supported benefits apply to weapons, so this choice is relevant when you have access to and use them.
How it works
It is selected from the XP-linked shrine options. The supplied evidence identifies the XP requirement and the two effects, but does not quantify either increase or specify weapon types.
When it helps
Consider it if you expect to use weapons and can spend the required XP.
