Oh, I know about that site, but it doesn't tell you much about training an all that, it just shows you a very good image of the maps, an what bosses there are to fight
Digifort is the best NQ2 site because all you really need are maps of places. You can still beat the game even if you are using a crappy skillset but without maps you could be stuck in an area for a long time.
i think its a good way to make np if you have alot of time and u dont want any risk of getting frozen with the abers, i only got the bronze trophie because i have no pacience but if i did i would def. play it over and over again
