Hey guys i have been playing on this awesome pking RSPS called Dustscape! This server you can upgrade weapons and armour so that when you pk you can hit higher. The way that you upgrade is by getting upgrade tokens by killing others. Each kill you usually get 1m or more of upgrade tokens, 100k pk tokens, and 2.5m. There are multiple shops at home where you can use the money and to upgrade a weapon all you have to do is right click the weapon and click upgrade. Here is a pking montage that one of the mods put up.
There is also automatic voting rewards!
