Add Artifexum spray chance to disintegrate

[GreaseMonk]

About the PR

As it goes, when you spray artifexum, a liquid of the artifacts, over other artifacts, it will activate.
However, there is the occasional chance that it will have enough power to create a portal strong enough to swoop the artifact back to it's planar world where it came from, however it also brought something back....

Spraying artifacts will now have 5-15% chance to destroy the artifact and spawn a artifact golem.

Why / Balance

Spray to get points made artifact research useless, no point in doing it if you can just put 50 on a rock and spray it.

this is a clever solution, i hadnt thought of this yet. I like it, adds the missing risk/reward thats needed to the spray system.

Is this ready or you still making changes?

Checkraze had concerns that this would be too much of a nerf and wants more player feedback after you made changes to artifexum before merging this.

It is ready for review.

You can use the magnets scan code to locate arti next to arti in range of 3 meters and only then have this % active

This will only effect multi spray then while making it no risk to none abushers of this issue.

If possible have this scan done when it's doing the activation to not scan none stop.
