Age of Wonders 4 Guide | 7 Biggest Mistakes To Avoid

Age Of Wonders 4 looks simple at first, but small mistakes stack up quickly. A few bad choices with expansion, diplomacy, or economy can quietly ruin a strong start.

This guide covers seven of the biggest mistakes you should avoid. You will see how to use Magic Materials, read AI rulers, squeeze value from Heroes, handle Grievances, plan for Victory Conditions, pick smart territories, and control upkeep so your empire does not collapse.

Mistake 1: Ignoring Magic Materials

Magic Materials are not just another Gold Vein or normal resource node. They are rare bonuses that give strong empire-wide effects. 

You often find them inside Free Cities, near City-States, or on guarded map nodes, sometimes next to an Infestation. When you vassalize a Free City with something like Astral Dew, you gain that Magic Material for your own empire.

Each Magic Material belongs to Ores, Liquids, or Plants. Ores usually boost Draft and experience. Liquids help Mana, Knowledge, and spellcasting. 

Plants often support Imperium, growth, and diplomacy. When you collect three different materials from the same group, you unlock a powerful Collection Effect on top of the normal bonuses.

If you skip Magic Materials, you lose free stats, faster research, stronger armies, and better income. Always explore, clear the guards, and claim those provinces early.

Mistake 2: Not Understanding Other Rulers

Diplomacy in Age Of Wonders 4 is built around Affinities, Personality, Preferences, Strategy, and Alignment. If you ignore these, wars and broken alliances will constantly surprise you.

Opposite Affinities dislike each other. Nature opposes Shadow, and Chaos clashes with Order. If your empire is heavy Nature and a neighbor is heavy Shadow, relations will drift downward over time. 

Their Personality and Preferences show what they like or hate, such as Alliances, Exploration, or aggressive moves. Their Strategy explains if they favor treaties, expansion, or conquest.

Alignment plays a big role too. A strongly Good empire will struggle to stay friends with a strongly Evil one. Check their Threat Level, their progress toward Victory Conditions, and score rankings. This helps you see who is racing for a Magic Victory, who is going for Expansion Victory, and who is simply stronger than you. When you know this, you can decide who to befriend and who to stop early.

Mistake 3: Forgetting Hero Loot And The Crypt

Heroes are more than strong units. Their gear can change entire battles. A big mistake is leaving good items unused because you do not use the Prison and Crypt system.

After you build a Prison and then a Crypt, defeated enemy Heroes (except Throne Leaders) can be stored as remains. In the Hero Overview screen, you can inspect these remains, claim their items, and equip them on your own heroes. You may sell the remains for Gold, but taking their equipment is usually far stronger.

Regularly strip gear from fallen enemy heroes and fill every slot on your own. This turns average armies into elite forces without spending extra Mana or Gold.

Mistake 4: Mismanaging Grievances

Grievances are the heart of War Justification and diplomatic penalties. If you ignore them, you can trigger huge Imperium losses.

You gain Grievances when someone settles near you, steals provinces, insults you, or builds Outposts close to your realm. You can also fabricate them. 

Declarations Of Friendship reduce Grievances you generate against that ruler by 40. Declarations Of Rivalry increase them by 40. Each Grievance has a severity value, shown by skull icons, which makes it stronger or weaker in the war score.

When you want to declare war, the game compares your Grievances minus theirs. If they have more reasons than you, the result is negative. 

That means an unjustified war and a huge Imperium hit, often around 80%. To fix this, you can Pay For Your Transgression to remove Grievances they have on you, or you can forgive your own Grievances to calm tensions.

Plan ahead: keep Grievances if you want a fair reason to attack, or buy them off if you need peace and stable Imperium.

Mistake 5: Playing Without A Victory Plan

Age Of Wonders 4 has several Victory Conditions, and your city placement should support the one you want. A very common mistake is expanding at random and then deciding on a win condition too late.

A solid base is at least three cities close together. This cluster is easier to defend and is ideal for Expansion Victory. In that path, you must control a big share of the map’s provinces before you can build Beacons Of Unity. 

Once you reach the needed territory, you can construct one Beacon Of Unity in each qualifying city, and you need three different cities with beacons to win.

Strong City Allies and Vassals help because their land counts toward your total at higher vassalage levels. If your cities are scattered or weak, reaching the province requirement and defending all three Beacons Of Unity becomes much harder.

Mistake 6: Choosing Bad Provinces And Improvements

City strength depends heavily on which provinces you annex and what you build there. Many early buildings have Boosted Unlocks that require certain improvements like Farms, Quarries, and Foresters.

If a city has no Quarry, not enough Farms, and too few Foresters, you will miss many boost conditions. Your buildings cost more production and unlock later. When you annex a new province, placing a Farm, Quarry, or Forester to hit those boost requirements can dramatically speed up your growth.

Aim to secure at least one Farm, one Quarry, and one Forester around each core city as early as possible. With boosts active, you build key structures faster and stretch your economy further.

Mistake 7: Dying To Upkeep Costs

Expanding too fast feels strong until upkeep starts crushing your income. You pay ongoing Gold, Mana, and Imperium every turn for units, Heroes, Unit Enchantments, and bad wars.

An unjustified war can cut your Imperium income so hard that you struggle to grow cities or unlock new empire skills. 

Heavy use of Unit Enchantments looks powerful, but every enchantment adds Mana upkeep. If your Mana gain cannot cover both spells and upkeep, you will be forced to cancel enchantments or stop casting when you most need magic.

Extra units and going over your hero cap push Gold upkeep even higher. Try to keep armies lean and effective instead of bloated. Watch the economy tab often, trim units you do not need, and avoid wars that give you nothing but penalties. 

When upkeep is under control, your empire can actually use the power it builds instead of collapsing under its own weight.
