New units. Their discussion and selection of upgrades.

I take back what I said about the Crystal creatures... (I actually liked them, but only for Haven in duels against groups of ranged units). In the game... the ability is too unpredictable... It's much more convenient to reliably hit two targets.

2 Lucky Scull "Dancing with Death" are no match for the new ones. They die quickly. There's nowhere to use their ability because they die halfway there before they can reach the thick of the battle.
