What makes the mastery system even more interesting is that, a few levels later, you're given the choice of adding a second mastery, letting you further diversify your character's skills and making him or her that much more unique. Hardened RPG players should be intimately familiar with the regular desire to reroll a character after discovering that a particular class isn't to their liking. The mastery system in Titan Quest sidesteps that by letting you cobble together your own custom character class, and, should you find that you're not really using some of the skills that you've spent points on, you'll regularly run into non-player characters that will, for a fee, let you reallocate skill points. The generally flexible attitude toward character development is definitely one of the more clever aspects of Titan Quest, and it goes a long way toward keeping you from ever feeling like you're stuck with yesterday's bad decision.​
