Death Knight
The Death Knight is a melee hero and, in my opinion, the Undead's greatest hero. He can both heal your troops and harm the enemies with
his Death Coil skill. If he is running low on hitpoints, the Knight can sacrifice a lesser unit to replenish his own health with the
Death Pact skill. Unholy Aura allows all friendly units close to the Death Knight to regenerate and move faster. His "Ultimate Skill",
Animate Dead, has saved me many a battle. Upon using this spell, 6 dead warriors are returned to battle for a period of time. REMEMBER
save this skill until you really need it, i.e. when you are down in units in an important battle to either protect your base or destroy
the ememies. Also, try to use it in an area where many strong units have fallen (such as Tauren) so you can use this skill to its full
power (getting 6 free Tauren is so sweet when devastating an orc camp muahahahaha)
