Slimeballs and slime blocks are absolutely critical to any kind of advanced Redstone contraptions. One issue with the current economy is the sheer lack of slime on the market. There are several reasons for this.

Slimes only spawn in 2 locations. The first is in swamps with light levels below 7 above Y 40. Due to the nerfs on natural mob spawn rates (which I do not suggest tampering with), they are nearly non-existent.
Slime chunks are the other method of spawning. About one out of every ten chunks will generate as a slime chunk. They spawn Slimes in large spaces regardless of light level below Y 40. There is no way to find a slime chunk on the server except by blind luck. There are tools that exist to help users pinpoint slime chunks, but they require entering a seed, which would be a very dumb move for the server to make in releasing it.
Slime is used in large quantities when it is in projects, meaning it is quickly used up.

So, I would like to add a slime chunk finder plugin.

What this does, is the user has a tool (that can be generated, or even sold in the /warp shop!) that is used to generate a map that sees if the current chunk is indeed a slime chunk. The plugin already has the config files to do this in two ways to deal with it. Either the tool set can have limited uses, and be sold in the server shop, or running a command version charges the player for each individual search.

This will not damage the economy in any way, but help it greatly. Yes, the individual price per slime ball will go down, but only because they are no longer a collector's item. Shops will have enough to actually stock their stores, and so forth. In addition, natural spawn are still nerfed, too, so it isn't exactly building a gold farm.

Plugin: SCF
