And Malenia finally goes down. I probably should have just used my mimic. ( probably took 10-15 hours.
Now its Radagon and Elden beast and that annoying cutscene over and over again.
On a side note, it’s crazy how much harder Malenia and Radagon/ Elden beast are in comparison to the other bosses. A league of their own. I probably wont be good enough to play the DLC.
In my view, Malenia is the most challenging boss fight in base ER. Radagon while not exactly a cake walk, doesn't have anything equivalent to the Waterfowl Dance, which just utterly destroys you, unless you know the specific timing & technique to avoid the attack.
If I recall, a few things work well with Malenia. Using the Barricade Shield neutralizes the WF Dance. The Bloodhound's Quick Step will allow you to retreat quickly enough to avoid most the of WFD allowing you to dodge relatively easy the final combo. Throwing a frozen pot will stop the move. Finally, at her height, run below her and circle to cause her to miss, and then dodge & dodge.
As to the DLC, if you're playing a non-OP build and plan to fight Mano on Mano with a normal weapon, it's very challenging, but also very fun and rewarding. I find the point where you engage in a prolonged dance with the boss to be the epitome of Fromsoft's boss design, e.g., Rellana & Bayle. For that alone, IMHO, the DLC deserves GOTY, because I've yet to encounter any other game with bosses so refined, nuanced, and rewarding when it comes to engaging in the dance. The music that accompanies the Rellana duel is just perfect and the fight a true masterpiece. I'd highly recommend fighting Rellana "fair" before utilizing the other tools at your disposal. It's really fun and I suspect most will find the challenge rewarding.
PS - Elden Beast is pretty easy once you practice how to avoid its AOE. Unlock, sprint away, and double jump the rings. Then, reengage, and it'll go down.
