Hello, everyone.
Today I was experimenting with Obliterum Forge and noticed that I could cast spells while using the forge.
Exploit was performed on my mage.
I started to cast Portal to [destination] mid cast I opened Obliterum Forge and started to move.
My cast successfully finished and I opened a portal around 10-15 meters away from where I started my cast.
(doesn't seem to be working with items like hearthstone)
Not very useful at the moment, but I'll experiment with possible uses of this bug in the future.
