Increasing skill ranks enables you to use weapons and talismans of higher quality levels.
Equipping gear of higher quality is necessary to be able to fight stronger monsters (low level weapons
have more chances to glance against high level encounters).
You increase in skill rank in a specific weapon or talisman type by purchasing ranks in one of its
associated Skill Feats. Each of these Feats grants you passive abilities that will be automatically applied
to your character as long as a weapon of that type is equipped.
