How do I become a "No loss" Player: Tips needed

[Zechnophobe]

Alchemy set is super awesome, I got two in my first run through. Wish it would notify you when it's ready to grant a rune.

I feel like paladins and Heirsarchs should be in reserve for fights where you incur losses. I almost always find them to just make combats drag on compared to dragons (hah, word play). A little stone skin, target or timeback and rarely will a unit be in danger of death. Ultimately I feel I end up using them to resurrect.. themselves.

I'm not finished with the first play through quite yet (wanted to try the Vampire a bit) but I've found zero places selling substantial black dragons or ice dragons. I think 2 or 4 black dragons in the entire game so far. Kinda sad. Next time I'll get 3 call colossus from the magic department and use those at various times.
