How do I challenge the dude in white armor? (Spoilers)

[Xalren]

I have 1149 Essence and that still isn't enough. I assume I need more?

[Serpit]

Yes, you need more. 1800 to be axact.

[Muketsu]

Not going to spoil anything, but oh boy, that area is not going to be fun at all :(

[Vladimir]

It's interesting, but the white palace didn't occur to me that hard at all. Sure there were quite nasty places which at the first glance look utterly unpassable, but with the help of hive charm I was able to finish it without restarting in an hour or so.

[Muketsu]

Yeah, I figured as much, so I used the same trick, with a bit of patience, but it's just not a fun area, not a hard one though.
