We veteran optimizers know that the Tier system (proposed by JaronK and endlessly debated) may be flawed, but it's still a useful tool for gauging basic competency comparisons between base classes, especially for less-experienced optimizers.
Most optimization goals revolve around making characters as competent as possible at their chosen roles. This challenge is to de-optimize a character. There have been such challenges before, but this one is a little more specific:
Construct a 20-level valid build (i.e., meet all prerequisites), using
the most updated base class tier list I could find along with
the tier system for prcs that has
the worst possible tier.
(I'm not saying highest or lowest because it's confusing.)
The final tier will be calculated thusly:
~First, perform a weighted average of all base class tiers, weighted by the number of levels of the class, to determine the base tier (B#). For example, a Rogue 3/Commoner 2/Wizard 4 would be (4*3 + 6*2 + 1*4) / 9 = 3.1.
~Then, subtract any prc tiering adjustments from B# (so, a tier adjustment of -2 would make B# 3->5).
This isn't a perfect algorithm, so if anyone else has ideas for how to deal with multiclassing, I'm all ears.
Alright, go to it!
