Imo Radigon and Elden Beast are more difficult than Malania.
With her all you gotta do is get the fukk outa the way of that special attack. Everything else is pretty easy.
Even now on new game+ radigon/elden beast gave me more problems than her.
respect your opinion. but disagree.
i knew what i needed to do to beat radhagon and elden beast after dying 3-4 times. i knocked them off about 30 minutes later.
radhagon is the final skill-check: if you've gotten by malenia and godfrey's final form, then it's just a matter of identifying his attacks, working out counters and being patient. the attacks look different, but he's not doing anything you haven't seen before from morgott/godrick/malenia/erdtree avatar. elden beast was EASY. if you've gotten good at killing dragons on foot, that thing is tame (outside of a couple attacks that do massive damage). and he doesn't really breath fire, so it's easier to close distance on him and get in some hits when he's running around the stage.
i actually think the fight against dragonlord p >>> elden beast.
it took me 2-3 hours just to get malenia's timing down. took me about 8-9 hours total to beat her. and i tried damn near every way to beat her: magic, long-distance cannon (there's a trick where you won't miss her with the cannon that fires great bolts), melee, summons. wasn't until i stepped my game/strategy up that i had a shot.
