this page is more active then hunter page, so ill post my golden hunter idea here.
For a golden skin, they should have a redcoat soldier with a musket. 200% dmg duff, 250% at lvl3, 300% at lvl5. The firerate is always 5 though. At lvl3 it should get a bayonet that attacks when waiting to fire another shot, and has the same dmg of the musket and a firerate of 1. At lvl 5 it should get a flintlock that does 1/4 the damage of the musket, and fires 2 seconds after the musket fires. So at lvl5 it would fire the musket, stab 3 times with the bayonet, fire the flintlock, stab 2 more times with the bayonet, and then the musket is ready to fire again.
Time to make a dmg chart. lvl0: 9 dmg lvl1: 12 dmg. lvl2:18 dmg. lvl3:21 dmg. lvl4:35 dmg. lvl5:72 dmg.
