Just curious however: can you break your character in NWN 2 like you could in NWN? What I mean, is, I completed every quest in act 1, 3, and 4 up to the fight with "A" (not sure how to do spoiler tags) and only missed a few sidequests in act 2 (that I couldn't find, or didn't fit my alignment) but ended up only being level 15 at that fight, and therefore, with no way to gain any more XP, and being too low level to succeed in that fight, essentially stuck.
It should be entirely possible to win that battle at level 15, so long as you have a way to survive that one nasty implosion spell that gets fired off.
In the NWN2 OC the vast majority of your XP comes from the main storyline so you won't be seriously under-leveled in the end-game. For Mask of the Betrayer, I find the campaign actually gets
easier as you go along since the crafting system is egregiously over-generous and the campaign is probably winnable even if you never leveled up once. For Storm of Zehir, the only point of no return is the final boss fight itself. If you save before that you can always leave and come back later.
Thanks,but what about the parts right before the final boss? It's not always the final battle that gets you, getting to the boss itself is harder in many games (God of War 2, I'm staring at you.)
It's a little hard to answer that with complete detail without giving spoilers. The actual "point of no return" in NWN2 OC is a bit nebulous since areas actually get closed off sequentially. When it comes time for the end-game, you will be joined by pretty much every single recruitable NPC you have ever encountered. Needless to say, that's a massive party. You'll have their support for raiding the final dungeon to reach - and then battle - the final boss.
RPGs seem to be worse in some ways, because the mini-boss encounters before the final showdown are often when they throw wierd abilities at you that didn't build your character to counter very well.
The game does have powerful mini-bosses right before the final boss, but they don't do anything you haven't seen before. The final boss is actually the one who has the weird abilities that are completely new and unprecedented. Once you figure him out he's not that hard, but he's pretty confusing the first time you meet him.
