Cellux and I are currently working on a script for assisting bots (all you have to do is run several trove clients, the script will do all the rest) which is basically controlling a few toons that just follow you and help you fighting and multiplying the loot (this allows you to get up to 64x the loot when farming skyknights).
The difference to multiboxing is that in this case the toons are scripted, and during multiboxing they are still under your control. Advantage of Multiboxing: it's legal (I have read the TOC and also asked a DEV who told me that as long as you don't use any automatism its ok).
Advantage of assisting bots: No desync (characters moving apart ect.) and also alot easier gameplay.
Here a quick comparison:
I had to record with a camera since running 8 accounts at once requires excessive amounts of PC power which makes it impossible to run fraps additionally.
This project is a WIP and we are not going to publish the code since jerks like xSubarashix grab code from others and then claim it's theirs. As soon as the trainer is ready we will update this thread, so stay tuned
