Summon Explosion (master dmg, summon pos)

[Erexo]

Hello there,
I was just wondering, how to create a summon that explodes upon death and deal its master formulas dmg.
I was trying to do something in onDeath, but I really dont have a clue how to do what I need.
Basically I need script that takes positon from summon, but formulas from its master or to make summon have same formulas as master.
Im using tfs 0.3.6pl1

Here is sample spell:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_EARTHDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, 39)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -0.6, 0, -0.7, 0)

arr = {
{1, 1, 1},
{1, 3, 1},
{1, 1, 1},
}
local area = createCombatArea(arr)
setCombatArea(combat, area)

function onCastSpell(cid, var)
    return doCombat(cid, combat, var)
end

Greetings,
Erexo.

Ive done it, just change variant in doCombat.

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_EARTHDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, 39)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -0.6, 0, -0.7, 0)

arr = {
{1, 1, 1},
{1, 3, 1},
{1, 1, 1},
}
local area = createCombatArea(arr)
setCombatArea(combat, area)

function onCastSpell(cid, var)
    return doCombat(cid, combat, positionToVariant({x=952,y=481,z=7}))
end
