In fact I think the entire game was to easy thanks to the enchants. I like the idea of enchants but with them you can become invincible and 1-2 shoot everything. I had to remove any kinda +damage modifier on weapons to even get a challenge, but even after that I couldn't die anyway as my HP regen was 2,7% per second and I had 1500 HP and life leeched 400 HP every time it procced.
Depends on class, I guess. I had a pure mage (INT maxed, spirit around 80) and sometimes it was a bit hard to kill crowds of skeletons 2-3 levels above, since my shields are pretty low. Yeah, it took usually 3 shots to kill the guy, but when there were multiple enemies, I had some challenge. As for bosses, well... I just jump and shot. When I grew tire of this, I jumped on tall rock or something like that and all enemies stopped, trying to calculate the shortest way to me on the plain ground, which actually doesn't exist.
As for the last mission, it DOES suck and boring, but easy if you fly AHEAD of the ship and fireball towers.
