# TAG INSTRUCTIONS
#------------------------------------------------------------------------------
# For Actors/enemies:
# <guard_anim: id>      Sets an animation for guarding
# <enemy_size: size>
# <actor_size: size>    Both control the size of the battler. 1 means normal.
#
# For Skills/items:
# <melee>               The battler gets near the target while performing action
# <cast_anim: id>       Shows an animation on battler before moving
# <melee_anim: id>      Shows an animation on battler after moving.
# <custom_pose: name>   Uses a custom pose animation, rather than the default
#                       magical/physical/item one.
