Chaos magic. Is it necessary?

Light, like any other magic, is always useful. But for an elf, learning 2 magic skills is too much. If you're going to develop him, it's better not to focus on Chaos (in my opinion). As for Chaos, I prefer to develop Empathy, Readiness (defense + attack), Luck, and Magic Affinity. Without Magic Affinity, even an elf might run out of mana with Empathy. Instead of Readiness, you can choose Mechanics or Logistics.
