To my understanding, no. This is because Luck IV+ previously guaranteed an Exotic Scroll or Technique Scroll or Vindicator each sealed chest opened. The NEW Tier 4 Luck guarantees a second drop.
Meaning with the chance of obtaining an exotic scroll is at 33.3% the new luck IV will add a second drop, also add 33.3%.
With 13 Exotic scrolls, 6 Technique scrolls and a Vindicator for some reason, the old chance of obtaining an exotic scroll was 65% (Might be wrong since I’m horrible at math).
While two 33.3% drops are in theory 66.6%, remember they don’t stack so it’s still less than the 65% chance of the old Luck IV with DSC.
I kinda missed on a lot of stuff here but I do briefly remember someone saying that when 1.16.6 dropped, Vetex accidentally forgot to remove the new technique scrolls that he hasn’t finished making, one of which was Blitz.
