Which monster do you like the most in Heroes 5 (level 4)?

In my opinion, druids are the most readily available and effective spellcasters in the game.

I agree. Druids are the best, especially at the beginning of the game, because with their lightning spells, they can take out many more monsters than any archers at level 4:smile54:. Druids can be built early; you only need a guild of mages to build them, and you don't even need wood (but elves need a lot of logs). It's true that they are mediocre as archers, but that's only with the regular ones; the higher-tier ones are quite good at bombing, so even in large numbers, they are not weaker than, say, vampires.
Also, lizards are good with their charge ability. With smart tactics, they can cause a lot of trouble for the enemy. First, we attack with them from a distance and eliminate an entire stack:smile13:. Then they just stand next to the enemy (especially effective against low-initiative units) and bite him. And if you also create some phantoms:smile07: and place them around one stack...
