I bought a vibro lance off the bazaar today, had nice damage on it and good speed. Then I noticed under Damage Type it said Electricity. Is this a bug or is it possible to make melee weps that do damage other than kinetic? Seems kind of strange to me.

Haven'tbeen able to test it on an electric vulnerable mob yet, to compare damage with a kinetic one. Or maybe I'm just completely mixed up about what damage type means. Anyone help me out?
