for me I would have to say barron he is so annoying with that "tick tock" attack its impossible to stop your guy from dieing so i ended up training to level effin 18 and beating the crud out of him hydro class (manna stealing abilitys) hint hint
for me it was this roach, i think it was named gregor.. that damned healing was so annoying.. i needed 6 tries for that..
some think that the hydra is quite hard, but i found a way (as a biologist class) to beat it:
the only thing that you need is the poison spell (anesthetic) over the toxicant form skill (i think it works with all poison skills, but i beated(??) this with that one).. the fire-head hydras on the sides (forgot the name) seems to be very vulnerable to poison so they dont have to be a problem.. if they die, the middle one starts stunning and, with less luck, they dont stun you.. only thing left to do is (guess what?) attacking with all you have..

very good strategy, but i have one thing to add.
the fire-head hydras are vunerable to your classes "element", with bio its poison, with hydro its ice and psycho its thunder.
Most of the times I get stuck it isn't even a boss... take the Baron for example... I beat him the first try but sometimes there are three enemies and they over power me and they are normal battles...
None of the bosses are that hard with a well-built Hydraulic, but the Baron took the longest because I chose the wrong equipment for Roald and Veradux.
