Worms drop acid(green) artifacts used to make antiacid armor

[Sokyra]

Worms attack with acid, so they should drop some acid related resource.

It could be used to make acid resistant steel used in power armor recipes or a new sort of acid capsules for example..

Another possible use : alternative way of making sulfuric acid....
