It depends what you're going to use it for. I only used it for RC pouch but I later found out Konduit client has the feature for free. Playing in HD for a month was cool though.
Rocky from thieving - took 1.5m xp after hitting 99
Phoenix - 10m fm xp after 99
Kraken pet - 6k~ kc
Hellpuppy - 5.2k kc for this one, it was rough lol but I made around 500m~from uniques
Thermy - 1.6k kc
I'm pretty content with my collection since hellpuppy was the one I was mainly going...
What kind of autoclicker was he using? I'm assuming he didn't use one with random intervals?
I've honestly probably gotten at least 60m+ xp in mage/thiev with autoclicking and never recieved a ban.
