i have a question for u guys: can you change a spawner that you find in dungeons? like blaze spawners in the nether cave spider spawners in mineshafts spider zombie and skele spawners in those little mossy cobble rooms? if you cannot i suggest that you should. buying a spawner and changing it costs $12500

As long as you have 7500 coins you can use /sr change <mob> on any spawner inside neutral or ally territory.

ah sweet killing the wither is gonna be alot easier now
