I also beat Melania recently and decided to go back to the Haligtree and collect the stuff I missed, thinking ‘this should be easy, I’m level 296 and just stomped the Shunning Grounds, I’ll be right in and out.’

That’s some hard shit, that Haligtree. Every other dungeon is daunting but ultimately manageable, but the door at the end (which there’s a way to skip) being guarded by two ballistas, at least three lightning knights and an Omen, and there’s another Omen, a Revenant and a Crystallian nearby? Brutal.
EDIT: Also noteworthy, it seems like you can farm Aeonian Butterflies near the Malenia mist gate, needed for Rotbone Arrows.
