Do Mob Grinders Work in Rising?

Hostile mobs don't spawn in rising

 

As Mel said, they don’t. But you can make mob grinders in mining. You can search for a spawner, buy access to a already existing grinder from a other player, or you can buy one in the shop. www.shop.ecocitycraft.com

 

I guess if you put grass you may rarely get some friendly animals spawning, other than that I am pretty sure you need to buy a spawner key or something like that

 

Yeah but they spawn very very rarely
