as for what it does, you remember that the devidians can just lift you off the ground and drain your energy, and you can't really do anything? this cane always you to do the same to your enemies
the staff is practically useless unless you plan on holding your enemies for long enough to have your boffs kill them, especially interrogators and medics. your better off just getting your heals from a sci boff, two medical tricorders, one vascular regen and a nanite health is strong enough to defeat most attacks, have 3 officers all with the same abilities and 1 from the engineering side with shield regens and support abilities, it makes the cane completely useless in any sense of the word, i do however keep it around for interference purposes only and nothing more.
