The acid isnt very strong these days. I would suggest taking all ten. At a death metal concert. Or maybe go out into the woods by yourself, take them all, strip naked (make sure there is an electrical storm) run around and try to start a fire before the acid takes hold and you cant start a fire because the tree's wont shut up. Ignore the imps, they only want your soul which is of no real value anyway.
ENJOY. *walks out thinking of the sheer terror, laughing mannicaly*
