Reign of Chaos: Alliance, Chapter 3: Ravages of the Plague
With Jaina by your side in this mission, you should have no problems. I recommend leveling Jaina’s Brilliance Aura, Blizzard and Water Elemental in that order, since Brilliance helps Arthas’s healing a lot. It also lets your priests going. You should have almost no casaulties if you remember to heal as much as you can and micro-manage damaged footmen away from the battle while Holy Light is cooling down.
Make good use of your footmen’s Defend ability. Note that Defend only slows their move speed and not their attack speed. This means that you can start defending as soon as you have reached the enemy units without any real drawbacks. The A.I. is not clever enough to hit-and-run defending footmen.
Don’t miss the Mantle of Intelligence +3. It makes Jaina even more powerful.
