I would like to add that there is a very slim chance you encounter a special event in the bramble that will allow you to gain an extra 5 HP or heal your health. The Bramble (or at least for me) has been fairly easy to take on mostly due to crabs. they don't do a whole lot of damage and all you have to do is block for those first few rounds and then it's quick from there. BE WARNED sometimes The Bramble will throw 3 hermit crabs and one of those mice at you and that can be hard to take out if you don't wield a proper weapon by then.
