During combat at the enchanted town, only units with Icon Life.pngTrue Sight may use a Ranged Attack from outside the 4x4 "town-proper" area at targets inside this area.

Wall of Darkness is an Uncommon Town Enchantment belonging to the Icon Death.pngDeath Magic realm. For Icon Mana.png 40 it may be cast during siege combat in a Town to surround the 4x4 "town-proper" area with a wall of shadowy clouds. Units outside this area may not make a Ranged Attack against units inside this area, unless they are enchanted with Icon Life.pngTrue Sight. Units inside the area may freely use Ranged Attacks against units outside the area. Both enemy and friendly units are affected in exactly the same way.

The same spell may be cast on a friendly town on the overland map to achieve a lasting effect: the Wall of Darkness appears in each battle fought in that town. In this case the Casting Cost of the spell is Icon Mana.png 200, and maintaining it requires an Upkeep Cost of Icon Mana.png 5 per turn.

Effects Edit

Wall of Darkness forms a completely black barrier of smoke and shadow that surrounds the outskirts of the targeted Town. The barrier is so opaque that units outside it may not make any ranged attacks at units on the other side. Strangely enough, the barrier appears to block light only in one direction - making it possible for the town's defenders to freely make ranged attacks against units on the outside.

Ranged Attack Barrier Edit

Wall of Darkness' effect is felt only during combat taking place at the enchanted Town. On the battlefield map, the 4x4 tile area representing the town proper is surrounded by a visible black-cloud barrier. This barrier indicates the town's perimeter.

Units outside this area (usually the army besieging the town) may not make any Ranged Attacks at units inside the wall (usually the town's defenders). Any attempt to do so results in a red error message appearing on screen, and no attack is made.

Whether the attacking unit is friendly or not doesn't actually matter though. Only the position of the attacker and the target matter. Units on the inside of the barrier may use Ranged Attacks freely against any target, as normal. The barrier does not affect these attacks in any way.

Immunities Edit

Units possessing Icon Life.pngTrue Sight from any source are immune to the effect of Wall of Darkness. Due to a bug, however, units with innate Ability IllusionsImmunity Illusions Immunity are not. This is contrary to the spell's in-game help.

Usage Edit

Wall of Darkness may be cast either on the overland map or during combat. Its effect is the same, but there are differences in Casting Cost, Upkeep Cost and long-term implications between these. Both versions may be dispelled during combat (with Icon Arcane.pngDisenchant Area or Icon Sorcery.pngDisenchant True). However, if the besieging army fails to take the Town (i.e. loses the battle), the overland version is only suppressed temporarily, will reappear after combat, and may continue to apply in subsequent battles.

Overland Version Edit

On the overland map, Wall of Darkness may be targeted at any friendly Town that is not already affected by it. The overland version of the spell has a Casting Cost of Icon Mana.png 200. It also requires an Upkeep Cost of Icon Mana.png 5 per turn, which is automatically paid out of its caster's Mana Pool at the start of each turn. If there is insufficient Mana in the pool at the time, the spell will dissipate immediately.

Upon casting the spell, the game automatically opens a pop-up window showing the town view. A few moments later, a long stretch of black clouds will appear near the bottom of this view, outside the City Walls (if the town has them), to indicate that the town is now protected by a Wall of Darkness. The dark barrier itself will appear during any combat that takes place at this town, so long as the spell remains in effect.

The caster of Wall of Darkness may remove it by examining the town's details and clicking on its name in the town's Enchantments list. This will bring up a confirmation dialogue for releasing the spell. The primary reason to do this would be in order to remove the spell's Upkeep Cost, thus conserving Icon Mana.png Mana for other spells.

Combat Version Edit

Alternatively, it is possible to cast an impromptu version of Wall of Darkness during combat. It is available for casting only when defending a friendly Town. This version of the spell has a Casting Cost of only Icon Mana.png 40. However, its effect will only last until the end of the battle, and will dissipate immediately afterwards. This also means that it has no Upkeep Costs, as it doesn't linger at all.

Acquisition Edit

As an Uncommon Icon Death.pngDeath spell, Wall of Darkness may become available to any Wizard who possesses at least one Icon Death.pngDeath Spellbook. However, its availability during the game is almost never guaranteed.

Customized Wizards possessing Icon Death.png11 Spellbooks at game creation may choose Wall of Darkness as one of their starting spells, in which case it will be available for casting immediately on the first turn.

Wizards who possess at least Icon Death.png8 Spellbooks, or Wizards with Icon Death.png11 Spellbooks who did not select Wall of Darkness as a guaranteed spell, will be able to Research this spell at some point during their campaign. Wizards with fewer than Icon Death.png8 Spellbooks have a random chance of being able to Research it. The chance for this spell to appear increases with the number of Icon Death.pngDeath Spellbooks the Wizard possesses or obtains during gameplay.

Wall of Darkness has a base Research Cost of Icon Research.png 680.

With at least Icon Death.png1 Spellbook, the Wall of Darkness spell may be acquired as a reward for winning encounters in creature Lairs, Towers, et cetera, or when conquering the Fortress of a rival wizard who has already researched this spell.

Strategy Edit

Wall of Darkness' effect is pretty specific - though it can be very useful in some situations, it is useless in others. This makes it difficult to decide whether to cast the spell on the overland map and bear its Upkeep Costs, or simply use it whenever necessary during battles.

On the one hand, Wall of Darkness is a great defensive mechanism for sieges. Enemy Ranged Attackers are always a nuisance, and the opportunity to reduce their effectiveness (essentially - neutralize them) is a great advantage.

On the other hand, Wall of Darkness does nothing to stop any other unit, and very few enemy armies (except, possibly, Dark Elf armies) consist of more than a handful of Ranged Attackers.

As a result, Wall of Darkness is usually better cast as a Combat Instant when the town is attacked by an army with plenty of Ranged Attackers, or contains a few very-strong Ranged Attackers. This conserves Icon Mana.png Mana, as the spell costs only Icon Mana.png 40 and has no further upkeep costs.

Again, when in a war with an enemy that deploys many Ranged Attackers, casting Wall of Darkness as a Town Enchantment may end up saving more Icon Mana.png Mana in the long run. But this would have to be a pretty bloody war - possible against Dark Elves (most of whom can use Ranged Attacks) to justify the increased costs.

Known Bugs Edit

Contrary to what is stated in the in-game help text, units with innate Ability IllusionsImmunity Illusions Immunity may not actually attack units inside a Wall of Darkness. This affects two ranged Fantastic Units by default (Icon Death.pngShadow Demons and Icon Death.pngDemon Lord), in addition to any Ranged Attack units turned into Undead creatures. Interestingly enough, the Icon Life.pngTrue Sight spell, which is supposed to grant this same immunity, works as intended. However, this will generally be impossible to obtain for a Wizard possessing the affected units.
