Help with Mage Focus Item Farming

[Beldon]

I decided to hit up Najena since I finally hit lvl 20 - to get my focus items.

My question is what part of Najena should I be farming? I thought only Goblin Warriors and Magicians dropped the focus items, but was told the Dark Elf Magicians drop them too (this is unconfirmed on my end).

Using this map of Najena, I was thinking of farming just SE of 2 by the waterfall (if I can at 20) but was told the Crystal Room (4) would be a good spot - if I could break the room.

Any advice would be appreciated.

Kill ALL mages, Room #4 has 3. They drop from them too.

Gators in cazic drop rate is much better

You'll get destroyed by everything short of the first 3 mages at level 20.
