Este script te deja hacer multiples hit no sé la compatibilidad por que lo probé con melody y no funcionó pero asumo que es compatible con takentai y el sistema frontal

este tag va en las notas del skill

(remplaza x por el numero de golpes)

# Multi Hit Skills (RMVX)
#
#  Author : Logan Forrests
#  With  : Mr G W
#  Date Created  : 20 August 2011
#  Date Finished  : 20 August 2011
#  Last Updated  : 03 November 2011
#  Latest Version : 1.1
#
#--------------------------------------------------------------------------
# Version History
#--------------------------------------------------------------------------
#
#  v1.1 - 11.03.2011
#      Introduces new paramters:
#        - allowing a missed or evaded hit to stop further damage calculation
#        - Critical hit factored into individual hits
#      Code updated to fit coding standards
#  v1.0  - 08.20.2011
#      Original release of the script
#
#--------------------------------------------------------------------------
# Description
#--------------------------------------------------------------------------
# Allows skills to be assigned a specific number of hits.
#
# For example, Quad Slash is intended to be a 4-hit physical skill. By
# specifying this in the Database, the skill would be calculated as if it
# was dealing 4 individual hits. Each individual hit of a multiple hit skill
# is calculated seperately with the damage dealt by each hit being cumulitive
# to provide the total damage dealt. This also means that the accuracy of
# the skill and the evasion of the target is considered on each hit and not the
# skill as a whole. Thus, of the 4 hits of Quad Slash, only 2 may hit and
# contribute towards damage.
#
# The messages associated with attacks missing and being evaded will only be
# shown when all hits of an attack miss or are evaded.
#
# Because the properties are kept within an items BaseItem class, it can also
# be used for Items as well as Skills.
#
#--------------------------------------------------------------------------
# Directions On How To Implement
#--------------------------------------------------------------------------
# Assigning the Number of Hits
# ----------------------------
# To specify the number of hits a skill has simply use the following the tag
# within the Note field in the Database of the appropriate skills:
#
#  <mhs_hits: #>  - where # is the number of hits
#
# It is advised that skills that are made multiple hit are given a lower than
# 100 hit ratio. Setting a skill to have a hit ratio of 100 will mean all hits
# will land unless evaded which may result in a largely unbalanced skill.
# This is, however, not required and skills may be set a 100 hit ratio if desired.
#
# Implementing Critical Hits
# --------------------------
# It is possible to assign a critical hit ratio, allowing a skill to sometimes
# deal a critical blow on any one (or more) or its hits:
#
#  <mhs_crit: c% d%>
#      - where c is the critical hit chance as a percentage
#      - where d is the critical damage bonus
#
# The '%' signs are optional and not required to function properly. It is allowed
# simply for aesthetic and readability.
# The value of c should be an integer value between 0 and 100;
#    0 being no critical hit chance, 100 being always critical.
# The value of d should be an integer value above 100.
#  Note: A d value of 150 means 150% or 1.5x damage dealt. This is to follow the same
#      calculation style as the default scripts. Thus, setting a value less than
#      100 will reduce the damage dealt.
#
# Ending Damage Calculation Upon a Missed or Evaded Attack
# --------------------------------------------------------
# To make a skill stop damage calculation processing when the attack misses
# or is evaded, the following tag can be used:
# 
#  <mhs_end_on_miss>
#
# No additional value is required.
# This particular additional allows one to create skills that are 'interrupted'
# should an attack miss somewhere during execution. Using this produces
# a more realistic* effect but can lead to a much smaller average in damage.
#
# *Realistic in the sense that the attacker is caught off-guard when an attack
# does not connect or is evaded by the target and can no longer continue the
# barrage of attacks he is delivering. Mostly used for close combat type skills.
#--------------------------------------------------------------------------
# Script Installation & Compatibility
#--------------------------------------------------------------------------
#
# Simply place the script in the Materials section of the Script Editor,
# somewhere above Main.
# If using this to extend GW Extra Skill Features, this script must be placed
# below that script.
#
# This script is based from GW Extra Skill Features and thus is compatible
# with it. It is also suggested that the GW Extra Skill Features is used
# with this script, also it is not necessary.
#
# This script overwrites the following the methods:
#  skill_effect
#      - Removes the accuracy and evasion checks from this method.
#  make_obj_damage_value
#      - Includes critical hit damage calculation
#          - The default value can be set within this script in the LF::MHS
#            module; custom values can be assigned on a per skill basis.
#
# This script aliases the following methods:
#  make_obj_damage_value
#      - Implements a while loop to allow calculating of cumulative damage
#        for multiple hit skills
#      - Includes accuracy and evasion checks for each hit
#        but only sets the @missed and @evaded flags if all hits of a skill
#        miss or are evaded.
#--------------------------------------------------------------------------
# Support & Credit
#--------------------------------------------------------------------------
# The script has been written and tested with no other scripts in place. As
# such, if you encounted any issues with regards to other scripts,
# first try to resolve the problem by moving this script around. If you are
# still unable to resolve the problem, feel free to contact me on rmrk.net
# under the name LoganForrests (no spaces involved) with the name of the
# script(s) you find no longer work when this script is included and the
# nature of the problem(s) so that I can begin to work on the problem(s)
# being caused.
#
# Credit must be given if used.
#
# Credit must also be given to Mr G W as this script is based and designed from
# their Extra Skill Features script. When used as an extension to the Extra
# Skill Features script, this script follows the same copyright restrictions.

Esto de compatibilidades es bastante chocante cuando no te sirven los scripts que necesitas xD, gracias por aportar... que este da un buen.... toque de um.... profesionalismo al juego.

Pues hace falta un scripter que lo adapte pero como cada script tiene su seccion de ataques multiples no lo adaptar
