Eventually, you'll also be able to travel with two henchmen, up from just one in the original NWN. Mercenaries are not only vital to win battles, but have stories of their own. As you learn more about your comrades, you'll discover new quests related to their backstories, as your interests become intertwined.
Based on Dungeons and Dragons 3.5 rules, NWN 2 will offer a more balanced and streamlined game than the original. For players new to D&D, this means that you'll gain abilities and strength gradually, instead of in big chunks. Unfortunately, getting carrots more often also means you'll be saying, "Just one more battle..." until you drag yourself into the shower the next morning.
