NPC Reward on Kill?

So i have a script that gives you Souls depending on how much % damage you did and it works for multiple people so if u did 90% dmg u get 90% Value and the other person gets 10%. This script only works if you do the damage with Melee Weapons such as swords. I have a ranged weapon and i want it to work for it too. Idk how exactly local Tag = Humanoid:FindFirstChild("creator") somehow has to be implemented in the script.

local Mob = script.Parent
local Humanoid = Mob:WaitForChild("Humanoid")


local PercentReq = 10 -- Has to do at least 10% of Damage 

Humanoid.Died:Connect(function()
	for i,v in pairs(Humanoid:GetChildren()) do
		if string.sub(v.Name,1,6) == "HitBy:" then
			spawn(function()
				print("Getting Percentage")
				local Percentage = (v.Value/Humanoid.MaxHealth)*100
				if Percentage >= PercentReq then
					print("Getting Character")
					local Char = game.Workspace:FindFirstChild(string.sub(v.Name,7))
					if Char then
						print("Getting Player")
						local Player = game.Players:GetPlayerFromCharacter(Char)
						if Player then
							print("Getting Stats")
							local stats = Player:FindFirstChild("leaderstats")
							if stats then
								print("Getting Coins")
								local coins = stats:FindFirstChild("Souls")
								if coins then
									coins.Value = coins.Value + Percentage * 2
									print("Gave "..Player.Name.." "..(Percentage*2).." Coins")
									print(Player.Name.." Did "..Percentage.."% Damage")
								else
									warn(Player.Name.." Coins Not Loaded")
								end
							else
								warn(Player.Name.." Stats Not Loaded")
							end
						else
							warn(Char.Name.." Not Found In Players")
						end
					end
				else
					print("Not Enough Damage..."..string.sub(v.Name,7).." Only did "..Percentage.."% Damage")
				end
			end)
		end
	end 
end)
