Ginormo Sword

The weird thing is, it's possible to kill yourself in all of the tests, even the wisdom test. Just make the slimes multiply a few times and dive in. You'll take damage as long as you're touching at least 1 slime per second.

well
even with 0 vitality, it'll take awhile to make it pop on you
it doesnt always pop on you or near you

the best is luck and str tests
touch wall - instant death (run to inn, and click trophy off, and back on, and do it all WITHOUT dying)

if you die, you have re-activate it running back to inn
otherwise, it wont work lol

Lamia (hard mode) also gives 330mil gold
the bats are about 21mil gold each

gonna try more stuff

edit: dang, many things give 300-330mil+ gold easily o_o
even something as simple as skele knight gives that much
