It might be best to fight a boss solo at least once before you summon, just so that you know what to expect when you walk through that fog gate for the first time... Or else you might humiliate yourself and waste everyone's time.
When I help players against this fight, I usually use 2 Reduvia daggers, with the giant hunt ash of war on a halberd that has bleed as an occult, using erdtrees blessing, with fire deadly sin, or I’ll use Black flame protection for more physical protection, I’ll use the frost dragon breath on the second phase to help with the extra damage
i hate it so much.. it happened to me 3 or 4 times to be summoned, being stuck to watch the cinematic and then instant death to the summoner... just don't summon anyone and try a few times solo to have at least an idea of the boss, cuz people like u just waste our time :(
I was summoned to solo her and technically did but when her health was legit 2 hits away the mf host decided nhee let me get in and died immediately cuz she was mid waterfowl 😂
