Entity not doing damage troubles

[TuxCraft]

I'm making a harpoon for my mod and the mechanics work fine, what doesn't work is the damage, the most important part. I modeled it after the arrow code so I throw the harpoon at a mob and it bounces off but it doesn't do any damage. Here's my code, please tell me what I've done wrong.
