# ☆ Script Calls
#-------------------------------------------------------------------------------
# level_skill(actor_id, skill_id, show = true)
# level_skill(actor_id, skill_id)
# gain_skill_exp(actor_id, skill_id, value, show = true)
# gain_skill_exp(actor_id, skill_id, value)
#
# actor_id = the id of the actor from the database.
# skill_id = the id of the skill from the database.
# value  = the amount you wish to increase the exp.
# show   = make show false to not display skills level change.
#
#-------------------------------------------------------------------------------
# $game_actors[ACTOR_ID].reset_skills_exp
# $game_party.members[MEBMER_ID].reset_skills_exp
# $game_party.leader.reset_skills_exp
#
# ACTOR_ID = the id of the actor from the database.
# MEMBER_ID = the party members id (0 = leader)
# This script call will reset all skills exp and level.
#
#===============================================================================
# ☆ Notetags ( default )
# For use with Skill Noteboxes only !
#-------------------------------------------------------------------------------
# <exp set: id>
# replace id with the id of the Exp_Set (defined below) that you wish to use.
#
# <growth type: id>
# replace id with the id of the Growth_Type (defined below) that you wish to use.
#
# <max level: value>
# replace value with the maximum level for that skill
# (cannot be higher than the Exp_Set hash size)
#
#===============================================================================
# ☆ HELP
#-------------------------------------------------------------------------------
# The default max level is the size of its Exp_Set[id] hash.
