Can't remember exactly, plus actually there is a lot of randomness in the game, so every time experience is different.
I think there were some in the Undead lands, plus some eggs. Then there was some quest in Demonis(?) that sent me to Dragon astral plane, there were lot's of eggs of red and green ones. And then in Elven lands (in the maze) there were a few places that sold like 30-40 dragons each.

My unit layout has changed many times to fit with both my suplly and the current area, but the following have been my key combos this far.

At the start i had priests, archmage, archers, swordsmen, and thorns (cheap and very powerful when combined with priests' bless)

Towards the IoF, i had basically the same except i had archers, swordsmen, guardsmen, sea dogs and pirates (both being in high supply and very useful)

Right now im in the dwarven lands, and have yet to get the knights from the dwarf king, so im running with Cyclops (powerful ranged tanks), cannoneers (pure rape with salvo), alchemist (not a huge fan at all of these guys but the supply and demand required me to use them), dwarves (these warriors arent the highest in number but are very strong and good tanks), and to fill in the last spot ive got miners which i use mostly like peasants as cheap cannon-fodder and rather powerful close range defender for ranged units when dwarves cant help.

Seriously, Kupperz, Fell, and Megakill. You guys could make a new thread and discuss about whose strategy is more effectives. Oh, back it up with video record of your tactic or something. Since I'm interested also to see that.

I tried dwarven axemen or whatever they are called - mid level melee fighters. Saved me in Demon lands. The stack was giving out 6-7K damage with very few losses on their side.

When using all melee with an archer, the units that can travel further like the miners were really effective. I used them once for the underground sea but wasn't receiving any bonuses for them since all my gear gives stuff to humans. Warriors having kids really isn't the greatest either. They give mana bonuses and it really isn't necessary to have mana with the warrior, or at least I don't really make use of it at all. I'm going to try the mage or paladin after beating the game to make use of all the units I pass up constantly.

Also, the sword I got that forces you to either upgrade it to the sword of light or sword of darkness was really badass once I got it as the sword of light. Helps a ton.

@megakill: yeah the dwarf warriors are one of my favs, and ive got the beer keg which gives +1 morale to all my dwarves so its even better. Gotta love those midgets :D

12 Arcdemons, 80 Demons, 150 Hunters(Elves),200 Inq. , 100 Horsemen, 120 Black Knights, 150 Necros ,Some Red,Black Dragons , this is my pool from wich i chose the most sadistic way to obliterate my enemies !:twisted:

As someone earlier pointed out: Royal Thorns

They kick major butt. I have 16 of em. I have a helm that gives +100% to Thorn damage. (Helm of Blackthorn) They are by far my biggest damage dealer & plus they can summon 400+ guys. I have inquisitors in my party so I cast the bless spell & watch out!

Royal Thorn:

280 HP
20-30 damage (mine is 40-60 b/c of helm)

With bless that means each is doing 60 damage. I'm just entering the dwarves caves. Just got done with Island of Freedom.

My first time through the game, i played as a Paladin on normal
Early game i used mostly human troops up. Bowman, swordsman, priest, archmage and guardsman. They die pretty easily but thanks to the resurrection spell i somehow managed to minimize casualty. Oh, i also tried the thorn hunters but their dying rate is too high and i can't ress them so i gave up on them. These served me till the IOF. There i picked up some sea shamans to replace my depleted troops since they isn't any except bowman in IOF. Shamans are pretty good units. Their ghost axe heal and their totems can distract the enemy. Their melee isn't bad either but i seldom got the chance to use them to melee.

Then at the dwarven lands, i met with the same troops supply problem so i swapped some troops with alchemist and cannoneer and at 1 time polar bears which turn out to be quite a tank.

At the elven lands i used elves, hunters, horseman, emerald dragons and druids. I used these to clear most of the elven and undead and demon land. However, i suffered heavy casualty at baal city due to the demoness swapping my ranged units out. So i reloaded and replaced them with demons (lol) and tried it again this time with better results. It basically become a messy battle with phantoms, summons, demon gates swapping here and there. Anyway, in the first place i intend these to be temporary units so i used them to clear the other city and all the other battles in the past which i considered as too much trouble. By the time i was done, i had only about 50% troops left and all that remain is the labyrinth which i havn't enter yet.

And so i did 1 more final (almost) restructuring of my troops into elves, hunters, druids, black unicorns, unicorns. Well, i love archers units so elves and hunters are a given. I also used the elven crown and got the elven princess. Druids give 1 morale to elves and can shoot too so i used that. I also found (very late) that all troops of the same race gives 1 morale too so i decided to do that. The sprites,fairy and dryads will probably drop like flies. The ents are tough but a little too slow and they can't be ressed. So the best choice are unicorns. Relative good melee ability, can be ressed and good against undead (Realised this a little late, should have used them earlier). So morale is at all time high now. Crits every now then with gizmo given extra turns, i proceeded to clear labyrinth and orc land without much trouble.

Until Hyaas himself. Unable to use my turtling strategy i decided to have some fun with my final battle. I went back and recruits all 4 dragons and ogre (filler). So i let them duke it out while casting mass dragon slayer and then armaggedon every turn after that. In respond the enemy also cast armaggedon (lol) so the battle ends pretty fast and 1/2 the army is dead but it doesn't matter at this point anyway.

In summary, humans troops are unexceptional and should be swapped as soon there are better troops available with the exception of horseman.

Dwarven troops are generally tough. Alchemist and cannonners are good for giving a heavy first strike before battle is met. Same can be said for giants but i find them more useful used by the computer than players. Miners and dwarves are pretty standard fighters i think (Didn't use them).

Elven troops are my favourite race. Elves and hunters are excellent ranged units. Druids so-so but they can also charm animals and summon bears (fodder). Their range is also area affecting so thats a plus. Unicorns are good against undead and pretty good on the offense too but die pretty easily. Ents are tough but don't really see much action actually. Never tried the sprites, fairy and dryads but i think i will try them for fun with the Ange's ring someday.

Undead troops i didn't use at all in the game. Facing them i think they are pretty mediocre units with the exception of the necromancer. Their advantage lies in the raising, life drain ability and immunity i guess. Bone dragons are the weakest for the dragons if it can even be considered a dragon. Maybe it is because of the items, skills and spells that gives player and edge over undead so maybe if player can use them to better effect.

Demon troops i think are the strongest race i think. My fav troops had to be the imps and scoffer imps. Their fireballs and strike and return ability is really good considering that their numbers are big. Cerberus is good on the offense but they drop fast. Demons are good melee and they can summon. Demoness i think is good for computer but not actually useful for players.

For the dragons, i think the emeralds dragons are the best actually since you can actually cast spells on them like phantoms and even heal them. They can also drain mp. They are weaker than the red and black but i think it makes for it with it.

Totally agree with the bolded part; I used Horsemen the whole way through the game. In general I think the units are well balanced due to the way Leadership works. Sure, Black Dragons are best, but they cost 2,500 in leadership EACH, so you won't have more than 10 ever.

I think the key to selecting units in this game is to have a mix of melee and ranged units, and most importantly to make best use of any available artifacts/equipment. For instance, I found Anga's Ring to be insanely powerful for female fighters, thus I used a lot of Demonesses, Sprites and Lake Fairies. I also liked the Undead's Black Knight. He is a tank. :-P
