[2022] Why does triumph not increase darius’ true damage? Bug or feature?

feature most likely, a lot of other damage amplifiers like weakness and champion tend to not increase true damage from my tests on olaf e after slowing with q for weakness.

Conqueror deals a % percent adaptive damage so you will get 10% physical damage on top of the normal true damage, so it is an exception due to how its damage amplification works
