Trying to make a region3 hitbox that doesn't hit the user too?

So I'm currently making a game where you pick up orbs, which give you power (a leaderstat value) and a punching system. The only problem is the punching system does region3, making it so when I hit something, I'm in the region 3 radius, so it hits me! Is there any way I can fix this? Please help someone!

Script:

Enabled = true
Combo = 1
Action = "Combat"

script.Parent.OnServerEvent:Connect(function(Player, Action, m,Power, V1)
    Enabled = true
    local dmg = 10 + Power * 1
    print("Got this far.")
    if Enabled == false then return end
    print("Got this far. 2")
    if Action  == Action then
        print("Got this far. 3")
        if Combo == 1 then
            print("Got this far. 4")
            Combo = 2
            print("Got this far. 5")
            local Track = Instance.new("Animation")
            Track.AnimationId = "rbxassetid://6024898273"
            Track.Name = "Anim"
            local Anim = Player.Character.Humanoid:LoadAnimation(Track)
            Anim:Play()
        elseif Combo == 2 then
            Combo = 1
            local Track = Instance.new("Animation")
            Track.AnimationId = "rbxassetid://6025098835"
            Track.Name = "Anim"
            local Anim = Player.Character.Humanoid:LoadAnimation(Track)
            Anim:Play()
        end
        wait(0.2)
        local Region = Region3.new(Player.Character.HumanoidRootPart.Position-Vector3.new(2,2,2),Player.Character.HumanoidRootPart.Position+Vector3.new(2,2,2))
        print("Got this far. 6")
        local RTable = workspace:FindPartsInRegion3(Region, nil, 20)
        print("Got this far. 7")
        for i,v in pairs(RTable) do
            print("Got this far. 8")
            local Deb = Instance.new("BoolValue", v.Parent)Deb.Name = "Deb"
            if v.Parent:findFirstChild("Humanoid") and v.Parent:findFirstChild(Deb) == nil and v.Parent ~= Player.Character then

                    print("Got this far. 9")
                print("Got this far. 10")
                game.Debris:AddItem(Deb,0.2)
                print("Got this far. 11")
                v.Parent.Humanoid:TakeDamage(dmg)
                print("Got this far. 12")
                print("Did ".. dmg .. " damage.")
                Enabled = false
            end
        end
    end
end)

I'm having trouble on line 38. Line 38 makes it so it doesn;t hit me, but doesn't hit ANYTHING else either.

Local script (not important but for extra detail):

Player = game.Players.LocalPlayer
repeat wait() until Player.Character
Character = Player.Character
mouse = Player:GetMouse()
Tool = script.Parent
multiplier = 1

Enabled = true

Tool.Activated:Connect(function()
    if Enabled == true then
        script.Function:FireServer("Combat", multiplier, Player.leaderstats.Power.Value, Character.HumanoidRootPart.CFrame*CFrame.new(0,0,-2).Position)
    end

end)

No error in the output, I was just wondering, thanks!
