I don't know enough of the Relic weapons to comment on is the HP weapon worth it or not. Losing 30% Elemental damage is a huge blow to anyone who doesn't run double Belial, though.1m per person.
That means 7.5m total off-element (5m from Hime resulting in 2.5m bonus) or ~8.6m on-element (5m from Hime resulting in 2.5m bonus * 1.45 elemental advantage = ~3.6m bonus).
There are methods available for us right now that allow us to get individuals to Burst cap, but I don't think anyone has done a 7.5m-8.6m Full Burst on Nutaku yet?There's a calculator in Sanathlig's toolbox for this... the problem is, how do you define "usually"? The moment you go over 50% chance? Or the moment you hit 99.99% chance?
I'd just like to point out that I've done 1k investment and didn't get the boosted SSR, so that's like ~33 rolls. I think I had a roughly 50% chance at that point, but I failed the coinflip. The chances have dropped a fair bit since then, due to the SSR pool being bigger now.
