Best & Worst Units?

[fable]

The best units are Ancient Vampires, in bat form. Their damage is low, but it's enough to get raised to full after attacking, even against overpowering enemies. They're prime target for sacrifice too. As a paladin on impossible, I rarely had to run around to replenish units. I try to keep a big stack of living units to last, alternating between casting sacrifice and mana spring, and using cloud of poison. Occasionally I used time back on the enemy unit to have more blood to suck. Fights can take really long but it's still faster than buying units. Normal vampires can hit harder but they have lower defense, from Haas' labyrinth I started using both. However, neither were good enough for the undead area or the final fight.

Other units I liked:
- demoness (to switch the vampires with an archer unit)
- dryads (good to preserve some blood for the constantly sacrificed vampires)
- shamans (to save a few hits with totems)
- red dragons (black ones can't be raised with sacrifice)
