local area = createCombatArea(arr)
setCombatArea(combat, area)

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

its does everything its supposed to, except sometimes it does way too high damage and sometimes like 20 damage, and it misses a ton (tested on trainers) i tried making my mlvl higher incase it was doing 0 damage, but sometimes it will hit like 12k damage i dont understnd it. coiuld someone help me get it somewhere between 500 and 1000 damage and also never miss? (like exori vis) thanks!

try this:

setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -3.0, -320, -3.6, -400)

 

[Omen]

is that an exact copy of what mine says..?

 

[EvulMastah]

No, in yours its "3.6" which means, that this spell will also heal. Gullfisk edited it with "-3.6" - now it will take health instead of adding it.
