I had to "die" to get into the undead 'guild'. Those units were very useful and let me kill the first contract, then I killed the boss.
It's been somewhat smooth sailing. Forget about 'no-losses', but I can't seem to find any other scrolls now. e.g. no one sells stone skin and I used my first two up in battle! Doh.
I'm actually doing somewhat ok in Impossible Warrior so far but using the evil undead.
No one likes me now though. Sniffles.
[edit]
Just beat the game, I didn't even finish the rest of the contracts because I was starting to run out of key units.
Used Undead Army
- vampire
- ancient vampire
- bone dragon
- black knights (woot!)
- cyclops
Scored around 1033.... but if I finished the rest of it, could have probably gotten a little higher.
