Currently the mod only has 2 functions, Explode and a Lightning strike.
If you do not have the write args OR the correct name it may show a crash in the server/Give an internal error. If that happens its fine, Looking to fix it soon.
6/18/2015 - Removed /explode command! 6/19/2015 - Added creeper and wither! (Warning! Wither will spawn! Player must be OP before it spawns!)
