 # material conflicts
 #
 # If you want to edit this file:
-# - You need to take into account that multiple conflict can be applied to an item
-#   (exemple: protection can be applied to chestplate AND should not have other "protection")
+# - A conflict will apply to every item except if in one of the notAffectedGroups group
+# - the conflict will count only if the user try to combine at least as
+#   many conflicting enchantment as "maxEnchantmentBeforeConflict"
