I've been using this amity order and found it quite successful: Belgar, Nelople, Mariam, Lashir, Mevo, Nerudo

Sometimes i'll switch it up and use this order instead: Mariam, Avet, Kuldu, Nelople, Humple, Mevo

I use this all the time, returns the most consistent Amity returns of 210-270.

I am 100% sure that they did something to this npc in latest patch 2017-02-15.

I used to have 90% success rate. I did over 200 atempts today, and I failed more than 50%, and I also recieved the "Fail sparks" almost 70% of all the atempts, Mostly 3-5 fail spark.

I also noticed the knowledge "Lashir" did not send out those "Next combo" ball animation to several slots, he now only sends it to one it seems :S
