New units. Their discussion and selection of upgrades.

2) Well, Wind definitely wins due to its agility, but in larger battles, IMHO, Death will cause more trouble...

I think Death is the better choice against the AI, while Wind is better against a human player.

5) Combat! Blindness isn't something to sneeze at! I've won many battles with it!

Light also has Blindness, but the main difference is that Combat has a magic resistance aura.
