I was curious... Can someone make a second/third knight on their main account and get a mist tank from the mail, switch to their main knight and use the energy they get after a while, then switch to their second/third knight and use the mist tank, then switch back to their main to keep playing? This was bothering me when I was thinking about doing that so I could craft my Spiral Scale set and realised that A) It may not be possible and B) I believe that this would fall under abusing bugs/cheats/hacks/etc.
So, what I am asking is: Can you have multiple mist tanks from second/third knights on the same account and will it count as abusing bugs/cheats/hacks/etc.?
This wouldn't be very efficient, but it would work.
In order to get a mist tank, you'll be needing to spend energy on your second (and third, and fourth) knights to get them into T2 gear for the Moorcroft mist tank.
When any knight on your account uses a mist tank, all knights can use the energy. This isn't an abuse. It's horribly inefficient, however.
