Look script:

area = {
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
}

attackType = 1
needDirection = false
areaEffect = 10
animationEffect = 4

hitEffect = 17
damageEffect = 10
animationColor = -246
offensive = true
drawblood = true

UltimateExplosionObject = MagicDamageObject(attackType, animationEffect, hitEffect, damageEffect,
animationColor, offensive, drawblood, 0, 0)

function onCast(cid, creaturePos, level, maglv, var)
centerpos = {x=creaturePos.x, y=creaturePos.y, z=creaturePos.z}
n = tonumber(var) -- try to convert it to a number
if n ~= nil then
-- bugged
-- ultimateExplosionObject.minDmg = var+0
-- UltimateExplosionObject.maxDmg = var+0

UltimateExplosionObject.minDmg = 50000
UltimateExplosionObject.maxDmg = 100000
else
UltimateExplosionObject.minDmg = (level * 2 + maglv * 3) * 2.6 - 30
UltimateExplosionObject.maxDmg = (level * 2 + maglv * 3) * 3.0
end

return doAreaMagic(cid, centerpos, needDirection, areaEffect, area, UltimateExplosionObject:ordered())
end
