RogueStealth

[windbell 0]

help me, why my rogue stealth stealth has no response.

<FightClassSpell>
      <FightClassConditions>
        <FightClassCondition>
          <ContionType>Buff</ContionType>
          <Param xsi:type="FightClassConditionStringBool">
            <Name>Stealth</Name>
          </Param>
        </FightClassCondition>
      </FightClassConditions>
      <SpellName>Stealth</SpellName>
      <Priority>11</Priority>
      <CombatOnly>false</CombatOnly>
    </FightClassSpell>

Is it wrong?
