I like the glacier, despite how tough it is (in fact, because of it) I drew up an elaborate graph with all of the classes and perks, detailing their effectiveness against each type of enemy. felt so good when I bet it.
I sketched it., with no photocopier. I can make you a computerized copy later, a bit busy now. and while I'm here, let me say that this is a fantastic little game you've got.
The swamp boss is kind of overly easy. I never get hurt once fighting him, it just seems a bit of a step backwards from the other bosses. Even the Ent is harder than him. Maybe you should make that bug guy actually move a little, or spawn lots of little bugs when he gets hit or something.
I actually find the desert boss rather easy, especially as a warrior or a priest. warrior's spin does huge damage to him, and priest can usually heal off the bulk of his damage.
You know, I now agree. In recent playthroughs, I have found that the difficulty fighting the boss with any class can be mitigated if you just put more thought into what you're doing. Staying close at the side of his head, swiping at him, while quickly maneuvering to the side if he charges at you usually works for me. Don't stay inside of him when you're taking damage, and you should be fine.
...unless your a priest, in which case you can literally stand inside the bit behind his head half the time and still come out with decent health. Also, has anyone noticed that the dying pieces, if you manage to hit them before they turn skeletal, hurt you? Oh yeah, and the Glacier boss is awesome for power leveling.
