Its still wrong, you can get Enchanted Essence before skill 50.1
But anyway, none of that explains easier ways of obtaining residue in large quantities, so come out with it instead of being obtuse. You could hunt it, but you'd need monsters that drop a lot of magical items and do a heck of a lot of them frequently.
I've never argued against it being being difficult and expensive, only against people saying its so easy, when its really not.
When you can explain to me how hunting titans, cyclopians, tsuki wolves, yomotsu warriors, etc, is difficult... yes, it's TIME consuming, but it's NOT hard. It's EASY. Especially for someone that's a vet... Yes, LARGE quantities. Lots of them. Maybe a couple thousand of them... maybe more. But it's still EASY. King's Tomb *MIGHT* be a step above easy, only because it can get crowded quickly and there's the possibility of getting trained, but nothing says you need to hunt there.
I've posted this before, but I'll post it one more time, just for your benefit -
While I was training up imbuing, I managed to acquire enough residue to go from 78ish to 120, and had a surplus of over 10k left. I managed to acquire enough essence to not only get my 120, but have a surplus of 1.2k left. Hunting King's Tomb and the surrounding area, I managed to get to 10k loyalty, and stowed away from a couple of dozen to several hundred different imbuing ingredients. After buying all my gems, I still had a surplus of 2m gold that came with farming... about the only thing I didn't get an increase on was iron ingots... and I started with over 100k of those...
Oh, and also took the char in question to 110magery, 100 mysticism, 110 eval, 110 med... the 115 focus was basically a freebie...
So yes, I will grant you, it WAS work, but it was work I chose to do as part of my enjoyment of the game. But it was anything but difficult... by golly, I'd go so far as saying it was
EASY
