These large bosses are also known as World Bosses. There are plenty of them, and they give a decent reward.

I think it's a bug in the API. The request seem right, and if you try to get another ID, e.g. 82853, you get a normal response. It might be that the item has been updated and no longer has that ID. It's the same with titles, my account has two 'invalid' titles. You have to make your program, so you are able to handle these situations, unfortunatly.

When levelling up your opponents grow stronger, and though you get stronger as well, it tends to feel like the combat is getting more challenging. As you unlock more skills and the opponents get stronger, it's important to consider which skills are most effective. If you return to a low-level area, it should be easy to feel the difference. What level are you, and what weapons/armor do you have?
