hit and run solo
death knight-death coil on workers(all races but undead)
he can also use unholy aura for quick get aways
also it helps to run shortly out of the enemies town if you are
attacked, then they think you wont come back, jump right back
in and coil another worker,and if you have healing potions or rod
of nec, you can death pack a skel and get 130 health(good with
ghouls on lv 3 cuz of 300 % conversion, thats 960 health
restored for just 120 gold and little mana!!!!!)

lich king-frost nova on workers(2 times)
dark ritual is good with rod of nec bought ot tromb of relics
so you can get more mana
frost armor can slow millita and reduce damage done to
skelles or use it on the lich himself to last a bit longer
at lv 6 death and decay is only good against people that
have no offence or else the can snipe you while you are
casting death and decay (4% damage every second its like the
opposite of a healing ward only 2 times stronger)

crypt lord-
