|Turns a targeted tile into a Volcano, potentially destroying specific assets in that tile, and subsequently providing a permanent +1 Power to the spell's caster.|
|As of Master of Magic v1.31, Raise Volcano is known to be malfunctioning in at least one way. Please read the Known Bugs section below.|
Raise Volcano transforms a campaign map land tile into a Volcano. The resulting destructive effects of this are numerous and long-lasting.
Transformation of a Land Tile Edit
Towns receive various bonuses from any tile within their catchment area (a 5x5 square centered around the town, minus the corners). These bonuses may include extra Production speed, extra Gold income, and an increase to the Maximum Population of the tile as a result of bonus Food. They also receive bonuses from Minerals on those tiles, if they exist.
When a tile is turned into a Volcano, all of these bonuses disappear. As a result, the town's output of Production and Gold may fall by some amount, and the town's Maximum Population (and hence Population Growth and/or Food production) will drop by a small amount. Minerals in a Volcano tile are immediately and irrevocably destroyed.
As a result of Food output decrease, one or more of the town's free Population may automatically be turned into permanent Farmers in order to keep its citizens fed. Also, the drop in Population Growth may result in citizens dying (negative growth).
Destruction of Town Buildings Edit
When this occurs, each Town Building inside the town must roll a random number between 1 and 100. Any Town Building that rolls a 15 or less is immediately destroyed. To regain that Town Building, the town must produce it again as normal.
Note that it is possible to cast Raise Volcano on the caster's own towns.
Power Bonus Edit
While the Volcano continues to exist, it will give a constant +1 Power bonus to the wizard that created it.
Due to the high cost of the spell, this increase in power is not cost-effective. It would take 200 turns for this extra Power point to generate enough Mana to pay for the spell - but then again Power can be invested into Research or Spell Casting Skill increase!
Volcanoes Reverting to Mountains Edit
Before patch 1.31, Raise Volcano was considered almost a game-breaker: It was possible to continue covering the world with more and more volcanoes, and over time the caster's power would grow to unbeatable levels. This is even more noticeable with the Armageddon spell, which does so automatically.
At the start of each turn, each and every Volcano on the map rolls a random number between 1 and 100. Any volcano that rolls 1 or 2 (a 2% chance) will degrade to a Mountain. Therefore, if the world map contains 50 Volcanoes at the start of a turn, one will revert to a Mountain (statistically).
As a result, Raise Volcano's benefits are somewhat temporary. Each volcano you cast will last, statistically, about 50 turns - repaying its own Casting Cost and perhaps a little more than that.
Therefore, when casting Raise Volcano it is important to concentrate on getting the maximum benefit - raising the volcano on specific tiles (especially underneath enemy towns) to cause serious damage to enemy economy rather than just for the Volcanoes' Power bonus.
A note about the degrading effect: when a Volcano reverts to a Mountain it also has a 5% chance of creating a new Mineral there. This may end up giving a benefit to the enemy, if you've raised the Volcano in their town catchment areas. Take this into consideration when targeting the spell.
Raise Volcano may only be cast on the overland map, for a basic Casting Cost of 200. It must be targeted at a land tile.
The spell may only be targeted at specific types of Terrain, as listed in the table below:
|Valid Terrain Types||Invalid Terrain Types|
Additionally, tiles containing Nodes may not be targeted by the spell.
The casting wizard's Power is also raised by +1 immediately, though this will only mean anything at the start of the next turn. Note that the distribution of Power into Mana generation, Research and Spell Casting Skill increase remains the same unless manually altered.
The new Volcano is permanent, and is not maintained by magic. Only the change itself is a result of the Raise Volcano spell. The spell runs its entire course instantly, and therefore may not be dispelled after it has been cast, and does not require any Upkeep Costs. There are ways to turn a Volcano into a more productive land tile, but they do not involve casting any dispelling effects.
Customized Wizards possessing 11 Spellbooks at creation time may choose this spell as one of their default spells before starting the game, in which case the spell will already be researched and available for casting immediately on the first turn.
Wizards who possess at least 8 Spellbooks, or Wizards with 11 Spellbooks who did not select Raise Volcano as a guaranteed spell, will be able to Research this spell at some point during their campaign. Wizards with fewer than 8 Spellbooks have a random chance of being able to Research it. The chance for this spell to appear increases with the number of Chaos Spellbooks the Wizard possesses or obtains during gameplay.
Raise Volcano has a base Research Cost of 680.
With at least 1 Spellbook, the Raise Volcano 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.
Raise Volcano has several effects, and can be used in a multitude of ways as a result.
For one, this is an excellent economic-attack tool that is significantly harder to reverse than Corruption. It both destroys a tile's production and permanently removes Minerals from that tile, so it may be terrific for preventing an enemy town from benefiting from such minerals.
It is also wise to cast this directly at enemy towns - especially large ones containing plenty of Town Buildings. The more buildings a town contains, the more chance there is to destroy at least one of them - and possibly more than one.
You can also use Volcanoes to slow down enemy movement by placing them along your borders. Remember of course that Flying units can cross over Volcanoes easily, as can Mountaineering units. Also, Roads constructed over Volcanoes allow units to cross them just as quickly as any other tile.
The increase in the wizard's Power is also a terrific bonus from the spell. The more Volcanoes you create, the more your overall magical prowess increases. Unfortunately, since patch 1.31, Volcanoes will eventually revert to Mountains and cease providing this power bonus. Use Armageddon, if available, to counteract this.
Known bugs Edit
Contrary to the 1.31 patch notes, the spell never creates a new Mineral when the Volcano reverts into a Mountain. Investigation of game code reveals that a new Mineral is created at the time the Volcano is raised instead, however it is immediately erased afterwards, because they applied the two operations in the wrong order. The 1.50 Unofficial Patch fixes this bug and enables the created ore to appear.
Raise Volcano will not change the movement costs of the affected tile. This means that ground units need the same amount of Movement Points to enter a tile as before the Terrain was changed. For example, a walking unit just needs 1 point to enter a former Grassland tile; or a forester unit just needs 1 point to enter a former Forest tile; or a waterwalking unit just needs 1 point to enter a former Swamp tile.
