Hello
Not sure if this is intended or not, but it is possible for mages to mount, Hearth and do almost all sorts of spells while moving.
The plan is to just cast your Ice Floes and then do whatever you feel like. That means that you can mount while moving / falling / swimming.
Finally it's possible to feel like a druid even tho you're a mage.
Then it's also possible to combine with the other known exploit about "not loosing stacks" when Ice Floes is used - Link Below

Searched the forum for this but couldn't find anything about it.
