Castle Improvements are a vital part of any efficient strategy.
You invest resources in your castle. Each resource type is worth a different amount of points:
As per the formulas, it takes exponentially more points to reach a higher bonus. Therefore, it is wise to build as many Diamond Mines as possible early on. Most players stop building Diamond Mines by day 25 of the round. Depending on your speed, strategy, and play style, players often have between 300 and 800 Diamond Mines.
However, Diamond Mines are not always the best building choice. See racial differences.
Despite having a unit that depends on a building, Dark Elves are often seen with DMs.
Goblins have a +10% bonus to improvements, meaning every 1 point invested counts as 1.1 points for Goblins.
There is debate as to whether Gnome are better off with Diamond Mines or more Ore Mines. Since Rockapults reach maximum DP at only 40% mountains (compared to 60% mountains for Icekin's FrostMages) and those 40% are easily designated for ore mines and homes, many players find room for DMs.
There are six parts of the castle into which the player can invest resources.
|Science||Platinum Production||20%||Useful if you have a good population. Otherwise, resources are better spent on Keep.|
|Keep||Maximum Population||30%||Always invest in Keep. It is the most beneficial improvement in nearly all cases. See Population.|
Magic Damage Reduction Mana Production
|40%||Makes your wizards (and Arch Mages) stronger and reduces damage taken by black-ops. Boosts mana production. Not commonly used other than dominions which specialize in magic and black-ops.|
|Forges||Offensive Power||30%||Often used, especially by races with inefficient or costly offensive units.|
|Walls||Defensive Power||30%||Practically always used, especially by races with inefficient or costly defensive units.|
|40%||Often underrated improvement. By increasing food production, you need fewer Farms which saves land for other buildings.|
The formula is different for Science and Keep, Forges and Walls, and Towers and Harbor.
- MAX: replaced by the maximum for the improvement (see above).
- POINTS: the amount of points you have invested in this part of your castle.
- LAND: your land size.
For Science and Keep and Towers, the formula is:
The formula for Forges and Walls:
The formula for Harbor is:
