SA Critical stun [First]

[Handy]

Gostaria de saber se tem como eu diminuir a chance do S.A. Critical Stun da Demon Splinter, ja tentei aki mas n consegui.
Na xml do sa esta assim:

<skill id="3016" levels="6" name="Special Ability: Critical Stun">
<!--
  Automatically generated from C3 client files.
  Need to be checked/fixed.
  Target is set to TARGET_NONE, skillType  to NOTDONE for server compatability.
  Descriptions:
  1: Temporarily stuns target into paralysis.
  6: Temporarily stuns target into paralysis.

-->
  <set name="target" val="TARGET_NONE"/>
  <set name="skillType" val="NOTDONE"/>
  <set name="operateType" val="OP_ACTIVE"/>
  <set name="castRange" val="-1"/>
  <for>
  </for>
</skill>

e na arma assim:

<item id='6604' name="demon_splinter_crt._stun">
  <for>
    <set val='342' order='0x08' stat='pAtk'/>
    <set val='132' order='0x08' stat='mAtk'/>
    <set val='4' order='0x08' stat='rCrit'/>
    <add val='4' order='0x10' stat='accCombat'/>
    <set val='325' order='0x08' stat='pAtkSpd'/>
    <enchant val='0' order='0x0C' stat='pAtk'/>
    <enchant val='0' order='0x0C' stat='mAtk'/>
    <!-- Enhances damage to target during PvP -->
    <mul val='1.05' order='0x30' stat='pvpPhysDmg'/>
    <mul val='1.05' order='0x30' stat='pvpMagicalDmg'/>
  </for>
</item>
