Side note - the third boss fight against that winged thing which keeps running away IS SO CRINGE OH MY GOD! Even though it was painful it was fun to finally kill it. With a lot of tryharding, save scumming, bring all the potions for decreasing sanity, for focus and so on, and RANGED MAICAL ATTACKS I was finally able to defeat it. I was hitting it from max range with wind ranged attack and thunder ranged attack, I think the boss got bugged because after 3-4 phases of teleporting away, it got close to me and then started to dig inside the wall straight upwards, literally, the game spawns health potions, stamina potions and brown crafting things (Binding Stone), use them as a throwable weapon against the boss, it does gazilion damage.
