You can't "adjust he ping". The ping results are what they are. It's a combination of physics, lag for echo requests leaving your machine, lag for echo responses getting back to you, and everything in between.
If you want to reduce your latency (that's what ping measures, along with reachability), see if anything is congesting your network, if your network is misconfigured, if your ISP is having issues, if your PC is overloaded, etc.
Wouldn't it be nice if we could salvage Ramaladni's Gifts, and the result of that would be a set of bounty materials from the difficulty from which the gift was found? I have stacks of these things that I have no need for, and it would make for interesting trade-offs in the early game.
