Finally found a use for the Battle Droids on my shelf, since I'll probably never be able to get them to stand- rearranged things a bit and put them laying down/hanging off and some of the clones- namely Delta Squad for now- standing victoriously atop them. Sorry to bring slurs into it, but as they say, "The only good Cl*nker is a dead Cl*nker."
Good question. I'd assume so, since it does for everything else. (I'm reminded of Halle Berry's Storm- "Do you know what happens to a Xenomorph when it's cut by a lightsaber? The same thing that happens to everything else.") As long as none of the blood gets on the hilt, I'd assume the saber itself would be relatively unscathed. At most, maybe a cool, unstable crackling effect like Kylo, but I don't see why it would necessarily.
