# D2Fileguide goes into more detail about how these are used
# the gist is 1 in (Quality - (mlvl-ilvl) / Divisor) * 128 of rolling each of these
# in the order unique, set, rare, magic, hiq, normal (and falling back on loq)
# further modified by MF after diminishing returns value (250 uni, 500 set, 600 rar) - which I believe is hardcoded
# and then the TC values
