Traitor Item questions & tips

[KikiMofo]

Not really a traitor item themselves, but only traitors have much of a reason to use them, the homemade pipebombs vary in power depending on what explosive you use in them. The order of power, from weakest-to-strongest is: welding fuel-black powder-plasmastone-erebite.

I haven't found any erebite to test them with but a plasmastone bomb near the center of the test chamber can send shrapnel into people on the other side of the crystal windows, and break a few as well. Welding fuel bombs are pretty weak, but can be useful if you drop them on a stunned victim or rig them with a mousetrap.

How do you put the plasmastone and erebite into it? Just stuff them in? Also how much is needed?
