Easy wins:
The AI is attracted to your hero in tactical combat. Use your hero to lure enemy units into a killing zone of ranged fire. For non-hero battles, place a ranged unit out front to become the lure. Retreat your siege engines from combat as soon as the wall is breached. They are too expensive to be destroyed by token infantry attacks.

Migrate friendly citizens to every city you conquer unless you are in a hurry or need gold immediately, in which case, you should just loot. Never raze conquered cities, unless it is a victory condition.

Monster lair reconnaissance:
Use the following trick to learn what kind of enemies there are in a monster lair or crypt. Enter it with a battering ram and choose “Fast Combat”. The “Fast Combat” screen will appear with all fighting units,including the ones defending the lair. Then retreat your battering ram from the battle.

Most powerful leader:
In scenario mode, when you use a customized leader give him Atk 7, Def 7, Dmge 6, and Life Stealing. He does not need anything else. Note: This is for a dwarf; other leaders might have 1 or 2 points difference on Atk or Dmge; do not get rid of Life Stealing or Def. You should also give him the following spheres: 4 Air, 3 Fire. Air has Chain Lightning, Haste, and Windwalking. Fire has Fire Halo and some good offensive spells. Attack enemies with your hero, He will be able to destroy almost anything. When he levels up, give him full Def then Wall Climbing and Round Attack. Do not give him Archery or some form of a ranged attack, because in automatic battles he will use those and Life Stealing will not do anything. It is the most important thing about the leader. When your leader has full Def and Wall Climbing, give him better Atk, Dmge, and Resistance. At about level 11, your leader will be strong enough to take on groups larger than 15 and leader’s bases. You should also give him abilities like Extra Strike and Parry later. Remember, spellcasting is not a large part of this leader. The best place to use this leader would be Oracles Eye, because there are plenty of opponents. At the end of the scenario your leader will be slightly higher than level 20. Remember to attack almost only with your hero.
