My config
#===========================================================================#
# Name: Loot																#
# Author: Kmacho															#
#																			#
# Instructions:																#
#   Here is where you set up the different types of item lists.				#
#   I set up an example below that you can easily modify.					#
#   Now, onto the important stuff:											#
#   																		#
#   ListName:																#
#     inheritance: OtherListName											#
#	  detailed: true/false													#
#																			#
#   ListName - The name of this list(used in the second line of a sign) 	#
#   inheritance - Will inherit the items from the list OtherListname		#
#																			#
#	detailed - Set this to true if you want to specify certain properties	#
#		of the items on that list. Know that this will make the config a 	#
#		lot longer, but will enable you to customize to your liking.		#
#																			#
#	  Detailed format:														#
#     items:																#
#       ItemNameOrId:														#
#         spawn: chance,min-max												#
#		  effects:															#
#		  - NameOfEffect,Min-Max Lvl,Chance,Splash,Extend					#
#																			#
#	  Undetailed format:													#
#     items:																#
#	  - ItemNameOrId,min-max,chance,randomEffect							#
#																			#
#	ItemNameOrId - Name or ID of the item									#
#	effects - Effects that could be applied to the item 					#
#   min - Minimum amount to appear if it passes the chance check			#
#   max - Maximum amount to appear if it passes the chance check			#
#   chance - The percent chance to appear at all							#
#	randomEffect - add a random enchantment/potion effect(defaults to true)	#
#	splash - Makes the potion throwable(only applies to potions)			#
#	extend - Extends the duration of the effect(only applies to potions)	#
#																			#
#	You can also set up per-world loot chests. When a chest is opened and	#
#	does not have a loot sign under it, it checks if the world is on this 	#
#	list. If it is, it will choose a random list of that world and be set	#
#	to respawn in the amout of time set on the world.						#
#																			#
#	worlds:																	#
#	  NameOfWorld:															#
#		time: Minutes														#
#		lists:																#
#		- NameOfList														#
