The official website of Heroes V has been updated with the list of racial special skills. Like necromancers had necromancy, now each of the six factions has a specific skill or even two. Wizards can create artifacts for creatures, Sylvan heroes can select archenemies, and warlocks can ignore magic resistances and immunities. The elemental vision of Dungeon heroes sounds particularly interesting. The damage of dungeon creatures will depend on elementals associated to them and their opponents as well as the terrain they are walking on. "Feng Shui of battlefield" as TheLuckyDragon called it in our forums.

Edit: The downloads page seems to have four new screenshots, but the resolution is quite low. Better versions of the images can be found at GameSpot.
