For some reason, simming with the Walk with the Ox potency conduit causes a noticeable decrease in TUF and increase in death chance %. If you compare the two sims with other potency conduits here:
against the sim with Walk with the Ox here:
you can see the difference. My hunch is that the CDR on the conduit de-syncs Niuzao from some high damage phase, causing the defensive benefit from having him out to be wasted. If that’s what is happening, then I guess it’s a valid result, just seems like it’s inaccurate since based on the rotation it’s luck that it has any defensive value at all. It would help if there was a way to see how much damage Niuzao prevents.
