Help!!! Bonus Critical on weapon without license???

[JeremyMunshi]

Hi! I recently signed up so i am new here so plz help me.

Few days ago ,in Uruga, i saw this dude selling a weapon with (+8%) critical! and no it was not just 8% critical it was something like 'critical 5% (+8%)' and the +8% was yellow! so i was checking a way to increase crit rates of a weapon and i came over the license thingy. BUT i found that the max crit bonus a license can add is only 5%!!! So there must be another way of increasing the crit rate of a weapon!

So my question is how?!? ?_?

Thankx in advance!!!
