These spells are used to duel players in a two step process. Here's how it works:
One player sends a spell to another player. The recieving player gets a notification and selects a second spell. That player sends his/her spell to the original player and the winner is generated randomly from experience stats, spell weakness/resistance, and level.
The forum is a great place to chat and exchange circle numbers, used to learn new spells.
Please note, this app is currently shut down due to abuse of the forums. This instead was a flame war caused by the sister apps Blood Wars and Powers, which are much less moderated and, in most peoples opinions (and mine) discusting and filled with perverted threads, comments, and posts. These have also been removed from the app store.
Me: Course! Mines 6572280!
Many people on Twitter/Facebook: Hey creator, when does the app come back up?? We've all been dying to know!
