yea ur right. i did some more tests with life orb out of sun / speed boosting proto and the rest of them lined up with it being 80bp + sun boosted + proto. it definitely isnt 120bp so i mightve messed up with my calcs somewhere since i was changing a lot.This math doesn't seem correct no? If hydro steam really did get a sun boost on top of a power boost, the multiplier would be 1.5 (Power boost) * 1.5 (Sun boost) * 1.3 (Protosynthesis) which is closer to a 2.925x power boost. Which is a whole .7x off of the difference in power we actually saw (2.283x). It seems significantly more likely that this has more to do with disparate damage rolls with a small sample size no?
i edited that part out but i left in the part about the umbrella's interaction with hydro steam in sun since that is actually implemented wrong.
i also realized the 33% decrease accounts for a proto boost + 50% drop.
