# 스킬의 사용에 필요 조건이 생깁니다.
# 이것을 활용하여
# 기술을 사용하면 불화살이 소모되게 한다거나
# HP가 낮을 때만 발동되는 초필살기 등을 만들 수 있습니다.
#
# 필요 조건은 스킬의 메모 항목에 표기하면됩니다. 
# 각 종류별로 하나의 태그만 인식됩니다.                  
#            
#                                                                           
# 무기의 메모 항목에 표기하는 태그:                   
# <weapon_type xxx>                                                         
#                                                                          
# 아이템에 표기 가능한 태그:                                           
# <include_battle_test> - 이 아이템을 테스트 전투에서 사용가능하게 해줌 
#                                                                          
# 스킬에 표기 가능한 태그:                                     
# <weapon_type xxx> - 해당 종류의 무기로만 스킬 사용 가능   
# <item_present id> - 파티가 해당 id의 아이템을 소유하고 있어야 스킬 사용 가능 
# <item_consume id n> - 스킬 사용시 id 아이템을 n 개 소비               
# <item_consume id> - 스킬 사용시 id 아이템을 1 개 소비               
# <hp_percent_exceed per> - HP가 비율 per 이상        
# <hp_percent_below per> - HP가 비율 per 미만 
# <mp_percent_exceed per> - MP가 비율 per 이상                                                     
# <mp_percent_exceed per true> - MP를 비율 per 만큼 소비
# <mp_percent_below per> - MP가 비율 per 미만             
# <free_hand> - 적어도 한 손이 빈손이어야 함                
# <dual_weapon> - 이도류 사용                      
# <two_handed_weapon> - 양손무기 사용      
#   
#
# 예를 들어:
# <item_present 3>
# <item_consumed 4 2>
# <weapon_type bow>
#
# 위의 스킬을 사용하려면 id 3 아이템이 필요하고
# 사용할때 id 4 아이템을 2개씩 소비하며
# bow 타입으로 설정된 (메모란에 <weapon_type bow> 라고 입력한) 무기를 장비해야합니다.
#

# Note:                                                                     
# This script also includes the function hands_free which returns the       
# number of free hands for a Game_Actor.                                    
#                                                                           
# Version History:                                                          
# 0.4 - test release                                                        
# 0.5 - can specify some item to include in battle test                     
# 1.0 - Bugfix and update to TagNote 2.0                                    
# 1.1 - Fix regressions
