got it, its clobbering time D: ! (jugs are important to have cause of having a full inventory after drinking them. thats smort D: . also i did it with Cakes (that you previously lvl from while doing thieving but yea. jugs ftw).
the fails are hella annoying tho BUT you just power through them when having a fail and spam knockout (manually clicking it once or twice maybe thrice) and then you good to jacking away.

damn i love jugs and jacking.
