[fa1thDEV]

Hello, how do I make the Ogre Spirit Totem heal me a little life, a style to the skill "Battle roar", I tried but it leaves me at 0 life copying the effect of "life" and "mul> maxhp", what line should I add?

<skill id="109" levels="1" name="Ogre Spirit Totem">
    <set name="icon" val="icon.skill0109"/>
    <set name="reuseDelay" val="120000"/>
    <set name="magicLevel" val="46"/>
    <set name="hitTime" val="2000"/>
    <set name="hitCancelTime" val="500"/>
    <set name="mpConsume2" val="21"/>
    <set name="effectPoint" val="438"/>
    <set name="target" val="TARGET_SELF"/>
    <set name="skillType" val="BUFF"/>
    <set name="operateType" val="OP_ACTIVE"/>
    <for>
        <!-- effect={
        {p_speed;{all};-30;per};
        {p_physical_defence;{all};30;per};
        {p_magical_defence;{all};30;per};
        {p_avoid;{all};-9;diff}}
        operate_cond={{equip_weapon;{dualfist}}} -->
        <effect count="1" name="Buff" stackOrder="1" stackType="possession" time="120" val="0">
        <mul order="0x30" stat="runSpd" val="0.7"/>
        <mul order="0x30" stat="pDef" val="1.30"/>
        <mul order="0x30" stat="mDef" val="1.30"/>     
        <sub order="0x40" stat="rEvas" val="9"/>
      </effect>
    </for>
  </skill>
