Rebalance artifacts

[Drago156]

So I'm gonna come back to this after a discord discussion we had, where ZJD informed me of how ridiculous some of the numbers are on arts. They are absolutely busted when they do roll successfully, and I can't count on even five hands the amount of rounds I've played in the last two weeks where someone had brought in or bought 20+ arts reliably and consistently... Artifacts are rather easy to come by in a number of ways, whether it be the ones spawning in artsci, those in debris and z5 that get telesci'd in half the time, the ones dug up by mining, the actual tons bought from QM, or from 15 or so spawning from a radstorm. They're far more common and easily acquired than I think people are realizing, and chance means fucking nothing if you have numbers, because you can brute force chance that way, very easily.

I'm also not a fan of powerful arts having anything below a 10-15 second cooldown, such as forcefields, teleports, ranged shocks, or gibbers. These are the arts that are incredibly life saving or ending with a mere button click, and that shouldn't be spamable IMO. Make people think more on how they plan to use their arts instead of just ending up with antags that spam kill or block everyone with an art or the griefers that do majorly irritating shit and just consistently get away because of their instant charge and many use artifacts.
