combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_HEALING)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
combat:setParameter(COMBAT_PARAM_AGGRESSIVE, false)
combat:setParameter(COMBAT_PARAM_TARGETCASTERORTOPMOST, 1)
combat:setParameter(COMBAT_PARAM_DISPEL, CONDITION_PARALYZE)

function onGetFormulaValues(player, level, magicLevel)
    local base = 250
    local variation = 0

    local min = math.max((base - variation), ((3 * magicLevel + 2 * level) * (base - variation) / 100))
    local max = math.max((base + variation), ((3 * magicLevel + 2 * level) * (base + variation) / 100))

    return min, max
end

combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

     function onCastSpell(cid, var)
local position = Variant.getPosition(var)
    local tile = Tile(position)
    if tile then
        local bottomCreature = tile:getBottomCreature()
        if bottomCreature then
            --return combat:execute(bottomCreature, var)
            return doCombat(bottomCreature, combat, var)
    end
        end
   -- end

  if target:isMonster() then
     --creature:sendCancelMessage("You can only use this rune on creatures.")
     player:sendCancelMessage(RETURNVALUE_NOTPOSSIBLE)
    player:getPosition():sendMagicEffect(CONST_ME_POFF)
end
    return
