Actually if you use ToM for farming, you are retarded. Because it inscreases normal drop rate by the same amount as rare drops, so basically the rates don't change (0.1/100 to drop shuta is same thing as 0.2/200), you will only drop more stuff/junk. In other words, it's like trying to find 1 red ball in 100 white *****, if you doulbe drop rate of everything you will have 200 white ***** and 2 red *****... So the probabilities remain the same. On the other hand, ToH increases normal drop by only 50% while rare drops are doubled (100%), so this one really does increse the probability to drop uniques.
Hope this was enough clear. ToM -> Only for grinding.
