Boar Attack Damage

[Zerrata]

I would like to know how to calculate how much damage a boar can do, depending on it's level. I'm just curious, because I want to know if all of the damage can be negated by a sufficiently high quality cutthoat cuirass and other leather armoring (leather pants, boar tusk helmet).

If anyone knows the calcuations for bears, foxes and other creatures that would be great too.
