How would i build up damage just like A bizarre day TimeStop?

I was going through the old abd scripts, i was trying to figure out how would i integrate the part where they built up damage

here is an example of the damage build up part i think?

elseif chr.Dodge.Value == true and game.Lighting.TS.Value == true and chr.RTZ.Value == false then 
repeat
	wait()
until game.Lighting.TS.Value == false	 
hum:TakeDamage(dmg)
lol(dmg)
elseif chr.RTZ.Value == true then
	rtzevent:FireClient(plr, player)
	negate()
	return	
end

here this is my TS script, trying to figure out how i would integrate it into my TS script

Building up damage is a matter of determining when damage should build up, and then figuring out how to unload all of that damage at the same time.

The first concept that comes to mind is to have one universal damage function for all stands in your game to use. This is to make sure they're all following the same rules about damaging (such as build-up) (This is a great opportunity to start using module scripts). Then you could put a BoolValue in ReplicatedStorage named "TimeStopped." This will make the value easy to access across all of the 900 scripts and localscripts usually found in jojo games.

This code is nothing perfect, but here's what the idea is. If TimeStopped.Value is true, then time is stopped. Instead of damaging the humanoid, store it in the DamageBuildUp table. Then, when TimeStopped.Value changes to false (meaning time is no longer stopped) unload all of the damage buildup and clear the table.

local DamageBuildUp = {}
local TimeStopped = game.ReplicatedStorage.TimeStopped

local function damageFunction(humanoid, damage)
	if TimeStopped.Value == true then
		table.insert(DamageBuildUp, {humanoid, damage})
	else
		humanoid:TakeDamage(damage)
	end
end

TimeStopped.Changed:Connect(function()
	if TimeStopped.Value == false then
		for _, argPair in pairs(DamageBuildUp) do
			damageFunction(argPair[1], argPair[2])
		end
		DamageBuildUp = {}
	end
end)

Any questions?
