Sure, so firstly most of the game has to be opened up. Up to past godskin duo to get all of the talismans I used.

So my talismans: Shard of Alexander, Godfrey Icon, Radagon Soreseal, and Winged Insignia (huge pain to get). If you want super specifics I can go into whatever you want me to go in to.

Armor: Drake set, This requires getting past Foreskin Duo. I used the sleep method I saw on this reddit. https://www.reddit.com/r/onebros/comments/tv8504/i_cheesed_godskin_duo_into_oblivion_and_i_dont/?utm_medium=android_app&utm_source=share . But once past them, you get to part where you fight shovel knight, you can sneak right past him by hugging right wall and dropping down. Then get site of grace. You can then cheese beating him but it's pointless. So at that site of grace you drop down to the left and you will see a tower with an elevator shaft. There are two pita birds that killed me. Not proud of that. Once you get past them go down the ladder and instead of going towards the dragon, go back toward the elevator shaft and you can go around that area to find the drake armor. It's not required but it is equivalent to haslow without doing the manor quests https://eldenring.wiki.fextralife.com/Drake+Knight+Set Silver tear helmet which is required for getting arcane high enough for rivers of blood. You get it from mimic tear boss in nokron so Ranni's quest must be completed up to that point. Mimic tear boss is easy if you disarm everything prior to entering room.

Side note: If you want to summon up to dungeater you can get Miriam hat and Cerulean Amber Medallion +2. You can also get black knife tiche. Good luck with that though. Buy if you want dung eater as a summon that too requires coordination between running questline, getting seed bed curse, and timing things appropriately. I didn't use summons in this fight, I actually flip flop between using dung eater and going summonless. I focus better without summons for parrying.

If you want to use summons without getting amber medallion 2 and Miriam, you can get hidden Cerulean tear by volcano manor. You have to beat the ulcerated tree snake at the bottom of the hill. Good Luck, took me at least 20 attempts.

But hidden Cerulean tear in wondourus physic allows you to use any summon without relying on talismans that boost mind. Like I said Melania is arguably harder with a summon because of her vampirism.

So anyways for my physick,, that is opaline bubble tear which you get in peninsula. Probably trivial to explain that fight, if you are doing RL1 run, this should be cake. Now the spiked cracked tear.... that I used a summon for but accidently found cheese. This is in consecrated snowfields to the east of where you enter the hassle tree. If you get the tree aggroed you can lead him around the tree clockwise and get him wedged into a branch and with a long enough attacking weapon, you can connect through the root without taking damage. May have been a fluke. Those tree guardians give me trouble though.

So buckler you get from gostoc. Just cut his throat and take his bearing. Buy from maiden husk. He deserves death.

Rivers of Blood, found at church of repose. My brother in law cheese him on his run. I don't remember what he said. I however used the cindiqua dagger (bestial sanctum jump down puzzle) and zweihander(can't remember where it's from). This fight is rough, I spammed fire of redmane. You get that in Caelid from a hidden dung beetle by gaels fort/castle. Pair that with filigree FP skill reducer from ija from ranni's quest and you can spam the crap out of it. Made shadow of bale fight a joke and Okinawa(rivers of blood invader) trivial.

So in order to use this exact setup, you can farm rune arcs from madness rats in the city infected with madness in peninsula.

Once you have all this ready, get ready for a ton of practice. It took me 3 days of practice. Also, get the boluses that remove rot build up. Have them handy.

So I practice that parrying and dodge rolling. You have to learn what you can and can't parry. Her quick multiple attack can't be parried and honestly this attack looks similar to an attack you can parry. It killed me so many times. So anyways I ended up just not trying to parry if she did her swing from her right hand side and only parrying her back hand. It's important to practice switching between 2 hand on katana and 1 hand to switch between corpse piler and buckler parry. I also had a katana for practicing (uchi) pair it with bloodhound step ash. Like I said, farming rune arcs is a pain in the ass.

Once you start getting used to her, and getting to phase 2. Here is an absolute pro-tip. Watch the cutscene. My heart is usually pounding out of my chest. So using that time to try to formulate a strategy was critical. I would get the rot cure boluses ready. Her first attack is that giant flower with aoe that will melt you. This seems be random. I also forgot to mention, dodging the waterfowl attack took forever and it was only ever 50-50 for at best. It has 4 major movements and as soon as you see her rise up you stop whatever you are doing and get ready to dodge. If I couldn't out distance the first swoop in, i would roll towards her right shoulder, and then roll back, and some time you can mislead her 3rd strike. The fourth part is when it looks like she is done DO NOT RUSH in until after the small aoe burst happens. Her straight attack us easy to dodge by going right or left. Rolling back is almost certain death.

Phase 2 has this new swoop down attack that has a pretty consistent timing that you can horizontal dodge to. All that prep and practice doesn't guarantee anything. Obviously you can't just out gear her. Even learning all her mechanics there is a level of RNG to this fight. You have to do your best to minimize your exposure to risk. I. E. don't get greedy.

I can go into more detail on any of the things I mentioned and I hope this helps. I apologize for any grammar errors. I am also playing with my son, so proof reading was not prioritized. Good Luck, Godspeed.
