Test server drop

Recently, I read about test server bug drop... It is fixed yet? Just need confirmation...

Which bug? The 100% drop one is, yes

Yah that one thanks for your confirmation... Also before it anything can you tell me where to get these easily?
-Doomatter
-Necrot
-Chaoroot

Edgy_Name posted a very useful bot for Doomatter.
Necrot should be farmed at deathsrealm with a boosted room.
Chaoroot will drop by the time you get what you need from Escherion, unless you're using Crag, in which case you farm the Hydra Heads.
