Well, this is great for anything you use with your totems ( Depending on the feats you have in it ) Every effect by the totems will be given twice because there is 2 totems.
How to:
1. Cast Totem of set, and click it again while its casting so you get the thing to aim with. ( The green range circle )
2. wait with the totem aiming marker until the first totem is about to be done casting.
3. Right before it ends ( Don't wait until the extreme end or it wont work ) just click on the ground to cast it.
4. Pull mobs.
5. ?????
6. Profit!
The way this works is, in AoC, you can cast a spell, and while its casting you can cast another one so they queue. It checks for the cooldown on the spell when you click on it, and checks if the spell has already been casted at the end of the casting.
This does not require any lag, I have a 53ms Ping while doing this. Timing is the key to this exploit.
This could also be done with any spells that you need to click on the ground to work. ( Quicksand, Totems, etc etc )
Here is a video of me doing it. - [AoC exploit] 2 Totems at a time for ToS ( Tempest of Set ) on Vimeo
