Nexus Clash

A 10 CP skill, child of Melee Combat and Ranged Combat (and HtH if eventually appropriate).
Increases damage dealt by [Light] weapons by 1.
A single purchase grants the effect for all types of weapons.

Could be expanded with other [Light] weapon skills, such as dual wielding (damage bonus for melee/guns), or scatter shot (AoE option for bow/thrown).

Eh
There are a few ways to fix light weapons, a skill sounds odd. I mean, this makes pistols overpowered.

Counter suggestion, maybe Light Weapons that don't have auto-reload properties (Everything except bow and gun) should deal 1 more damage than they currently do?

Low damage of Light weapons is a deliberate tradeoff.
