Archangel's Smite: Needs fuel (charged klein star, arrows, cobble/dirt, other EE fuel). Also bugged in SMP and won't fire arrow packs. Right-click function seems to work.
Cannons: Horribly buggy, wouldn't touch with a ten-foot pole, as it tend to relocate items and such on you after using it.
Energy Condenser: How does it not work? Read: How are you setting it up?
