Send damage upon players from item

[Nemphis]

10.77
TFS 1.2

So i have made this chest that goes away from existence after an X amount of time after first use.
(WORKS)

After that it starts an addEvent(WORKS) that will remove the chest(WORKS) and cast a spell upon its foes.(DOES NOT WORK!)

So far no good. This is what I've come to and it doesnt work at all..

local closeEpicId = 18473
local openEpicId = 24376

local area = createCombatArea({
   {1, 1, 1},
   {1, 3, 1},
   {1, 1, 1}
})

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)
combat:setFormula(COMBAT_FORMULA_SKILL, 0, 0, 1, 0)
combat:setArea(area)

local function boom(player, toPos)
   local item = Tile(toPos):getItemById(openEpicId)
   if item then
     toPos:sendMagicEffect(CONST_ME_FIREAREA)
     item:remove()
     combat:execute(player, item)
   end
end

function onUse(player, item, fromPosition, target, toPosition, isHotkey)
   --local itemPos = item:getPosition()
   if item:getId() == closeEpicId then
     item:transform(openEpicId)
     
     player:say("Detonation set to 5 seconds.", TALKTYPE_MONSTER_SAY, false, false, toPosition)
     addEvent(boom, 5000, player:getId(), toPosition)
   end
   return true
end

Apprieciate all the help i can get

I am not familiar with latest TFS's but I am almost sure it is

combat:execute(player, Variant(toPos))

also you should check if player still exist in the event
