Towers can be temp-banned, ultra-banned, or perma-banned. You can make any entity that can inflict banning. Banning removes the tower and all of it's instances from the screen, and makes you unable to use it.
Temp-Ban[]
A temp-banned tower will be banned for 25 turns, unless the entity says so.
Perm-Ban[]
A perm-banned tower will be banned for the rest of the game.
Ultra-Ban[]
This ban is not reversible by anything. It happens in special missions.
WARNING!!!![]
All banning and banning related concepts are references to Minecraft and the Noob Adventures series. It is not intended to insult the wiki admins.
