Any tips for not!Kalameet SL1? Where the hell do you get Preraise?

In a few more words, I've been doing BS1 SL1, and while most of the game has been very fun, these last few bosses are really pushing it. The hardest things I've killed are Prayer Master and Elizabeth. Currently getting my ass kicked by the Black Dragon in the DLC area.

My setup evolved through the run, but tl;dr I went from the Dagger to Storm Ruler, using resin stacking and crestfallen's ring—and Broken Shackles in case of Storm Ruler—to kill bosses from 51% HP to 0 in a turn or two to skip their undodgeable phase 2 attacks. Most bosses are completely harmless >50% HP (Behemoth, Prayer Master, even Ellie) if you just Evade every turn.
The issue is that the dragon gets his unavoidable shiny eye attack already in phase 1, and can do it twice in a row (popping Withstand, which is the usual counter), and he also requires the anti-debuff ring for the fight which cuts my damage in half, making any rushing attempts completely dead in the water. I remember Preraise, but I don't remember where it was found. I got the boss to ~40% once, but I don't really want to retry for an hour more, praying for no 2x Eye. He's also immune to Sleep cheese.

I remember at least one anon doing it a week or two ago itt, but I don't want to cheat and look up the full solution.
Picrel is my default Storm Ruler setup, for this boss I had to swap Broken Shackles for Undefeatable.
