Voice of the Dragon skill-worth using ?
 

Seeing that this skill is located at the final tier of Mind tree, I'm curious about the efficiency of it.

Also what does the "animals" in the skill description define to? Is Beholder animal ? Is dragon animal ?

animal will be griifins woulfs bears and such ... dragon is dragon ..

Well, I've got a stack of Black and a stack of Red in my army, and the additional boosts to crit, and stats makes a very nice difference.

as far as I remember, the black and white horses from the elves are also animals. what I really don't like in AP is that you can finish it and never find manny troops. in my first run I couldn't find manny elves, undead and lizzards. in Legend this was less of a problem.

What are MANNY troops?

The opposite to feww troops.

I think the troops are very random?
Since some people claim to have both red and black dragon at lvl 5, and i am at 20 now and only had 1 green. And i explored it all so far.

If you explored it all, you would have found green dragons on Elon, a ton of red/green/black dragon eggs on Shatterra (including Ulthrax) and Rehau, as well as a bunch of T-Rex eggs on rehau.

Red/black dragons eggs spawn here and there as well, like montero, tekron, nameless island. On nameless island you will find a few bone dragons eggs as well.

Yes, both troops and items generated randomly, I was rerolling a warrior and find out that the king has the same 6 items in his stock D:

My Warrior game, I found red dragons (4 of them) on Verona, at just about the time that I got 2000 leadership, they were godly.
