What is better in a 1 unit army - 1 red or black dragon

[TemjinGold]

For me it depends. I keep both because I like the Red Dragon's flame breath thing better than Black's as you can use it out of harms way. I can also phantom reds if needed or stone skin/heal. Heal can be useful as reds are much tougher than trolls minus the regen.

Haven't done Mage yet, but I would say Red, because of Mana Spring. Toy with the enemy at the end, let him hit you, spend a whopping 1 mana to heal. End the battle with all your mana. Next battle, have some rage to go with that mana.

It's easy to do the mana regen thing with one BD. I'm also up to level 43 and have been using similar tactics as DGD.
However, at the start of a battle, i usually cast Demon Portal, then when they emerge, cast Stone Skin and Mana Spring on them. Then i let them take a beating. If there are lots of ranged units or Shamans, then a level 3 Target on them also helps.
So while they're getting the crap beaten out of them, your BD is free to soar around and open chests etc. Towards the end of the battle, you can use the BD's Fire Breath on the stacks around the demon to get your range back up if you have the Paladin's Holy skill maxed.

Arg, just realised, Is it necessary to get the pet dragon that gives you +1 initative to dragons? I got The +1 int pet dragon. Is there an item that gives you +1 init for flying creatures?

[travelingoz]

If you're going for the one dragon strategy then it certainly can't hurt!

[Zechnophobe]

Just get Adrenaline instead, and choose the dragon that gives +crit chance.

Red dragons always. They can be resurrected and can be improved by spells. Besides, red dragon are good against black dragon, but black dragons are not than good against red dragons (RD Are fire inmune). And, the red dragon special hability is more useful than the black dragon (almost for me). Maybe i always use red dragons cuz i have paladins and inquisit, but i really found em more useful than black dragons. I just changed royal griffins for assasins, and i almost never used the tank units lol, i only summon the avenging guards and let em to do the work. But god, i run out of royal griffins but assasins are amazing -.-. I love red dragons, but i dont use em too much, only to block enemy's way or for using the RD Hability.
