2 Dracon, Mallasa, and Vayshan. Well, basically, I play as Eruina (because the starting abilities are great, and the special ability is good) or as Vayshan (cool start). If I were to write a general build for all three races, it would be like this:
1. Offense: Cold Steel, BB, Retribution
2. Chaos: Ice Bolt, Cold Death, Lightning Bolt.
3. Leadership: Rally, Haste Aura, and Diplomacy (although I don't always take it).
4. Education: Either go for Mentorship (Cunning) or Intelligence, Dark Revelation, and Arcane Blessing.
5. Here, either go for Sorcery (Secret Knowledge, Unstable Mana, and something that gives +2 to spellpower – I have an English skill build) or Luck (up to Sorcery, but for Vayshan, definitely Luck).
6. If the map is large, I definitely take Logistics: Scouting, Quick Mind (then in Education, you need to take Decipher Secret), and Surprise Attack.
Don't judge me too harshly; I'm not a master at playing as the Elves. I specialize more in Sylvan!
