yeah, so i got through the crypt and now i don't know where to go next. i read about some swamp on some official forum but couldn't find one. all i can find is a forest with a road blocked by a fucking troll that i don't seem to be able to kill. the forest also leads to some kind of glacier with some ice trolls that i also can't beat yet. tried killing one from afar with fireballs. it just came closer one step at a time and killed both my mages.
The swamp entrance is behind the troll, yes. And you don't need to use the forum for directions, all the important quest information is recorded in the journal (forums may be more pleasant to read though, I give you that).
Explore the town, get some more equipment and/or spells - you should have enough money from the crypt to get at least one spell and some armor. A certain spell makes fighting the troll quite trivial. One particularly effective tactic is to turn Dog into a tank, place your main char behind him and fireball the hell out of the troll (don't forget that you can split the party and make a formation before starting the combat).
There is another area you can try to take on at this moment, it's arguably harder than the swamp, but manageable if you abuse the out of combat fireball sniping. You need to talk to some NPCs in town to get there. If you go that route, try to get Dog to level up as soon as possible and raise his Spd to 30 so that he'd get 2 actions per round - that makes a huge difference.
Two more areas can be entered from the forest, but one requires another party member, and the other requires special protection that you probably can't get at the moment (i.e. it's not gated, but you'll have a hard time surviving the process of getting it).
