Normal bow:
Code: 
23:33 You see a bow (Range:6, Atk +1).
It weighs 31.00 oz.

No damage

Edited bow:
Code: 
23:34 You see a +3 bow (Range:6, Atk +10).
It weighs 31.00 oz.

No damage

(no erros on sources)

I don't know of any way to do that, unless you're using some sort of upgrade system that you need to get the attack of bow at all times, it won't matter.
Just insert the value of the attack of your bow into the script and it will work the same way.

I found this from awhile ago.. It uses the attack damage of the weapon and distance skill.
Not sure how you'll add magic level though.
Might have to create two different combats, like you attempted before.
https://otland.net/threads/burst-arrows.4723/
Code: 
function onGetPlayerMinMaxValues(cid, weaponSkill, weaponAttack, attackStrength)
    local attack = 28
    local skill = getPlayerSkill(cid, CONST_SKILL_DISTANCE)
    local level = getPlayerLevel(cid)
    local damage = (attack / 20 * skill * 2 + attack + level / 10) / 10 * 1

    return 0, damage
end

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)

You don't have
Code: 
setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetPlayerMinMaxValues")
in your script.
