# ** Notetags for Enemies
#------------------------------------------------------------------------------
# For VX and VXA user can use notetags at Enemy Tabs to determine 
# food / drink recovery rates    
# (notetags configuration will be prioritized):
#
# <recover hunger by percent>
# <recover thirst by percent>
# <hunger: x>
# <thirst: x>
# <increase max hunger: x>   # fixed value only
# <increase max thirst: x>   # fixed value only
