This mod adds a block that increases a chunk's HeatMap considerably to attract Screamer Zombies. This is so players can make a less laggy screamer zombie farm. No more placing a bunch of campfires/torches/forges to achieve the same goal! It is craftable from level 1.

It gives your server a unique flower planter that, when installed in the world, increases a chunk's heatmap within two to three minutes in real time and begins spawning screamers! Simply pick it back up and wait 1-2 minutes to stop them from spawning. It's that easy! The block has increased durability of 20K so even if exposed it can take damage the zombies deal out. But you'll have to repair it before you can pick it back up. The repair material is just plain old Concrete Mix!
