Personally, I'm all for it requiring stacking for a number that high, so you can't just apply the highest number immediately, or a lower amount of resist reduction, since just docking the scaling of the sword would end up relegating it to just being a sword used for synergy. But, imo, blood spike and scarlet twister were just things that brought a sword that for it's ability has been pretty underrated into the limelight more - it's not specifically just how it works with those spells that I'd imagine to be the issue.
