Can I tag a player without using Local Script?

I have an NPC that I want to give xp to a player upon its death. Sadly, I cant seem to tag the player who kills it with a normal script, but the npc wont work in a local script, any ideas?

local Target = script.Parent.Target
local enemy = script.Parent.Parent
local RS = script.Parent["Right Shoulder"]
local LL = script.Parent["Left Hip"]
local RL = script.Parent["Right Hip"]
Punching = false

function Walk(Part)
	 if enemy.Humanoid.Sit == true then
		enemy.Humanoid.Sit = false
	end
	for repititions = 1, 20 do
	for pose1 = 1,10 do
		LL.C0 = LL.C0 *CFrame.Angles(0, 0, 0.1)
		RL.C0 = RL.C0 *CFrame.Angles(0, 0, 0.1)
		wait(0.1)
	end
	
	for pose2 = 1,10 do
		LL.C0 = LL.C0 *CFrame.Angles(0, 0, -0.1)
		RL.C0 = RL.C0 *CFrame.Angles(0, 0, -0.1)
		wait(0.1)
	end
	end
	
end


function Chase(Part)
	if Part.Parent:FindFirstChild("Humanoid") ~= nil then
		Target.Value = Part.Parent.Name
		for chasing = 1,400 do
			if chasing == 10 or chasing == 20 or chasing == 30 or chasing == 100 or chasing == 130 or chasing == 200 then
				
				 local x = Instance.new("Part")
       			 x.BrickColor = BrickColor.new("White")
       		 x.Material = "Neon"
       		 x.CanCollide = false
       		 x.Transparency = 0.6
       		 x.Size = Vector3.new(8,8,8)
       		 x.TopSurface = "Smooth"
       		 x.BottomSurface = "Smooth"
       		 x.Shape = "Ball"
       		 x.Parent = Workspace
             local fd = script.fireDamage:clone()
             fd.Parent = x

        y.maxForce = Vector3.new(math.huge ,math.huge ,math.huge)
        y.velocity = enemy.Torso.CFrame.lookVector*115

        x.CFrame = enemy.Torso.CFrame*CFrame.new(0, 1 , -10)
        x.Parent = Workspace
        y.Parent = x    
        game.Debris:AddItem(x, 6)


			end
			if Punching == false then
			enemy.Humanoid:MoveTo(Part.Parent.Torso.Position,Part.Parent.Torso)
			end
			wait(0.5)
