#==============================================================================
# ■ 附加状态后 普通攻击消耗SP
#------------------------------------------------------------------------------
# 　使用方法：在状态名字里写[SP消费 xxx]来使用
#   例： 毒[SP消费 50]    => 每次普通攻击消耗50SP
#        沉默[SP消费 50%] => 每次普通攻击消耗一半SP
#   备注：有多个状态时，优先计算百分比扣除，再计算定值扣除。
#         多个百分比扣除会取最大百分比。
