Chaos magic. Is it necessary?

Personally, I only use Chaos magic everywhere. It has the most powerful spells.

You're a masochist, because Chaos magic doesn't work well with Elven magic at all!))
Elves need light magic, then yes, it's awesome...
Although in 3.0, upgrading to a fast, enchanted ballista has become easier; for this, you can level up Chaos or Summoning, because bees or a golem with knockback are truly powerful!
