That was a really tough fight! Harder than Sierpes for sure. My hands are shaking... In the end it helped me a lot a combo of Romance to the crimson mist and Big toe made of limestone. Plus fire defences.
Now I'll continue with Miriam challenges. Then I will finally fight Crisanta.
Edit: I beat the game with true ending and 100%. It was fantastic. I adore the visual style, music, bosses and the catholic mythos. Some people criticize the platforming (lamp jumping), but I didn't find it weird or anything. I highly anticipate the sequel now.
Glad to hear the boss fights continue to be challenging. This is one of the games I feel like I'm trying to beat out of pure spite. Does anyone else feel that way? There are some enjoyable moments but they feel rare. I just made it to the mother of mothers area and am trying to push through.
I find the challenge fun actually and I like the game quite a lot. The problem is that some areas without a proper gear are relatively unfair (Lady of the Charred Visage for example). But when you find the right combination of rosary beads, prayers and mea culpa hearts it gets much more easier. And to discover the right strategy is part of the fun for me.
