Rare tokens for armors in few days
place: Den of Crowmen - hardmode
Start hard mode
kite the big bird while you are killing the small one
when the small one is close to 10% (when he is about to turn to unattackble), chain stun/fear him and kill him while CCd. This will end up in epic loot. Then reset the big boss. It will this way take around 5-10 minutes per rare token. Also the AA xp will be insane.
YOU WILL NOT GET INSTANCE COOLDOWN IF YOU DONT KILL THE BIG BIRD
Failcom has also been banning big time (if i remember correctly TEMP banned, but it could be full) for this. So know that when you do it.
