i did immediately guess the gimmick cuz there's no way you'd use dalig for just a single-target boss fight!
the meta knowledge part of it is neat though. unlike doll i actually didn't get any woofy drops for a long time but i was like... i know these fuckers are gonna drop some healing eventually right? lo and behold, precious dog meat. thankfully the one carol i encountered 1) immediately got zerk'd by dalig's badass scriptures and 2) dropped a sacred blood that let me get the rest of the way through
but, i do think i like this less than dalig's first go-around. it was satisfying to succeed but the dungeon is purely a monster tripwire this time -- not that i, craze, of all people am going to complain about that, but in this particular case i found the gatekeeper puzzle to be more compelling, especially when sharing the game with friends and not telling them shit. some chests to lure you off the path might have helped (i know the struggles with switches in the time limit there lol)
re: your reply to doll, i do think a slower burn fight would work better because it would make dalig's attack spell drain her way more overall on the expected first try. i actually spammed it plenty and still managed to get through.
edit: i did not make it clear enough how much i liked QUOTE SCRIPTURE as a new tool though. really loved when like, each enemy got a different status effect. offensive oration that felt sticky and useful was fun
