You aim to master four elements, earth, wind, water, and fire. Each adjust the dynamics of combat and expose enemy weaknesses. It’s a system that wouldn’t be too difficult for children or casual game fans to pick up, but it allows for enough experimentation to keep someone more obsessive from going comatose. What might be difficult for newbies is the learning curve. After an easy enough introduction, the difficulty spikes suddenly."
