Olá amigo, vá em seu Spells.xml e Coloque isso:
<instant name="Antidote" words="exana flam" selftarget="1" aggressive="0" lvl="8" maglv="2" mana="30" soul="0" exhaustion="1" prem="0" enabled="1" script="antidote2.lua"><vocation id="2"/><vocation id="1"/><vocation id="3"/><vocation id="6"/><vocation id="5"/><vocation id="7"/><vocation id="4"/><vocation id="8"/></instant>
Vá em spells/scripts cria um arquivo antidote2.lua e coloca dentro:
local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, 0)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_FIRE)
function onCastSpell(cid, var)
return doCombat(cid, combat, var)
end
