random weapon [axb] (+c)
a = base of the weapon, higher the better. Until you hit the "Big Five"
, a higher base makes for cheaper upgrades, and a more efficient output
b= damage multiplier. it doesn't mean x2 will do twice as much damage as an x1, but it will deal a decent bit more damage. higher multiplier, higher damage dealt ^_^
c= CTH modifier. On top of DX, + (also known as pth) can increase your end chance to hit. Chance to hit is calculated as a percentage. With a decent DX advantage over your opponent and a good amount of + on your weapon, you can often get CTH of over two to four hundred percent. With a 50% CTH, you will hit half the time, and miss the other half. With 250% CTH, you will hit twice every time, and get a third shot about half the time. enemies using Evasion
and/or Displacement boots
can also modify your CTH negatively...
