#   sources: ### Possible entity types of damage source, see
#https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/EntityType.html
#            ### By default a damage from all sources will be changed
#            ###
#            ### Type of source should not be a projectile, see
#https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Projectile.html
#     - <entity-type1>

#     - <entity-typeN>
#
#   excluded-sources: ### Excluded entity types of damage source
#     - <excluded-entity-type1>
#       ...
#     - <excluded-entity-typeN>
#
#   targets: ### Possible entity types of damage target, see
#https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/EntityType.html
#            ### By default a damage from all targets will be changed
#     - <entity-type1>
#       ...
#     - <entity-typeN>
#
#   excluded-targets: ### Excluded entity types of damage target
#     - <excluded-entity-type1>
#       ...
#     - <excluded-entity-typeN>
#
#   causes:  ### Possible damage causes, see
#https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event
#        /entity/EntityDamageEvent.DamageCause.html
#            ### By default a damage with any causes will be changed
#     - <damage-cause1>
#       ...
#     - <damage-causeN>
#
#   excluded-causes:  ### Excluded damage causes, see
#     - <excluded-damage-cause1>
#       ...
#     - <excluded-damage-causeN>
#
#   formula: <expression> ### Formula of target damage modifiers calculation,
#                         ### see description below
#
#   use-source-statistics: true | false ### Use statistics of damage source
#                                       ### instead of damage target
#                                       ### Default value is 'false'
#
#   user-info: ### Format of user-visible information about damage modifiers
#              ### Should have one token to handle float value of multiplier
#
# ==== Formula definition ====
#
# 1. You should use JavaScript syntax
# 2. You can use JavaScript Math module functions, see
#    http://www.w3schools.com/js/js_math.asp 
# 3. Previous damage value will be passed via $X variable
# 4. Additionally you can use Player statistics, but only if 'targets'
#    equals to [PLAYER], see
#    https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Statistic.html
#    Type of statistics should be 'UNTYPED', see
#    https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Statistic.Type.html
#
# Examples:
#
# 1. Set a damage to constant:
# formula: 10
#
# 2. Double a damage:
# formula: $X * 2
#
# 3. Increase a damage depending on count of killing mobs: 
# formula: $X + $MOB_KILLS * 0.1
#

# Powerful creeper
creeper:
  sources: 
    - CREEPER
  targets:
    - PLAYER
  causes:
    - ENTITY_EXPLOSION
