#  To use this script, simply tag anything with features with the tag
#  <no target> in the brackets.  A target with this feature cannot be the
#  the target of anything until only non-targetable battlers are all dead.
#  You can also tag enemies with the tag <never target> and these enemies
#  cannot be targetted at all.  They do not need to be killed to win the
#  battle.
