My guess would mean restriction of abilities on specific maps, given the context? And if it is, well, that went… well.
To zombies map builders, it’s extremely annoying when people use abilities that the the map builders don’t want them to use. For example shaman on Cryptic Castle. (I made the health chest cost low for a reason!) What if the map builders can just ban abilities for their maps? After selecting the arena, /zability ban [ability name] And to unban, /zability unban [ability name]
