Artifact Shenanigans

[SL the Pyro]

I found a freeze ray artifact that put down a 5x5 area of ice and froze anyone in that area in an ice cube, and caused a decent chunk of the station to rage because they couldn't figure out who was doing it.

Protip: you can use those magic artifacts from inside vehicles/closets/etc. I once flew around in the Strelka icing the Escape Shuttle. The amount of rage generated from them not being able to find the source of the ice was hysterical.

I'm assuming that leading humans to harm is just as forbidden as directly harming them.

You assume incorrectly.

The gist of it is that you can't force humans to touch the artifact (i.e. locking them in a room with it until they touch it). You can suggest them to touch it, you just can't force them. Anyone that agrees to touch it is taking their life into their own hands and thus exercising their own right to hurt themselves, so it doesn't conflict with Law 1 that way.
