This spell is somewhat of an anomaly in the series of create room spells as it also creates the exterior of the room. It creates a complete tower including battlements if desired. This tower is created from a cube with a side length of 10 feet per 3 levels of the caster: an 18th-level wizard could create a tower from a 60-foot cube. Thus, this wizard could, theoretically, create a 180-foot high tower with a base of almost 35 feet square. This would obviously a very unstable tower, thus the normal rule is: the base has to be at least a square of _ the height of the tower.
Thus, in our case the wizard could create a tower of approximately 40 feet square up to 120 feet high. The walls of this tower are made from adamantine and require 2 points of structural damage per level to get a breach in a 10?10 feet section and an additional 3 points per level to collapse a 10?10 feet section completely. The walls are up to 1 inch per level thick. The tower can be made to collapse if one levels loses more than _ of its structural points or if more than 3 levels lose more than one tenth of their structural points. Anything in the tower at that time will most certainly be crushed (unless absolutely immune to magical, +5, metal). The tower can have up to one door per 10 full levels of the caster. The number of floors will be determined by the height of the tower with up to a maximum of one floor per 10 (partial) feet height. This is also one of the room spells which are obviously used for combat purposes so they don't vanish if used for combat. The tower still cannot be sold - in that case the whole tower vanishes in a puff of smoke. It contains one full battlement with merlons, one small ballista per 5 full levels, one shot for each ballista per level, one light catapult per 10 full levels, one shot per catapult per 2 levels, one large siege pot of oil or lead including fire for heating and the lifting mechanism, 10 arrow slits per level, up to 1000 square feet of interior walls per level (not including the floor and ceiling area), and up to one iron bound wooden door per level in the interior, whereas the external doors are full adamantine doors with over 20 structural points each. The doors are magically sealed with wizard looks which open either to a special command word or by the caster's desires. In addition, they can be locked normally with the internal locks of masterful quality (-75% to lockpicking chances).
The tower is in itself non-magical. Thus, it cannot be collapsed with the normal use of an anti-magic shell (unless the shell is laid directly on the targeting point of the spell). Mordenkainen's disjunction has either its chance against an artifact to destroy it or its chance to dispel it, whichever is lower. Dispel magic will only work if the caster himself casts it on the targeting point of the spell.
The material components are one large solid cube of pure adamantine of 3 inches per level per side length. Into this cube have to be merged (with no space between them) one diamond per floor level desired inside (of no less than 10,000 gp each). The metal should cost no less than 1000 gp per inch side length (an 18th-level caster has a cube with 54 inches per side length (4'6", which is more than a cubic yard of metal weighing a lot more than 20 tons), which makes 54,000 gp for the cube and at least 10,000 gp for at least one floor. This component can be used during preparation, but the spell has to be cast during the following 1 month per level time. If not cast during this time, the material component is used up completely. As this spell is memorised, it can be dropped for another spell, but the material component used in preparation is still lost. If the material component is used during the preparation, the casting time is only 2 rounds, otherwise it is 3 turns. The block of adamantine is the targeting point of the spell. It will always be found at the base in the centre of the created tower. It will be teleported there even if the caster does not know the teleport spell. It will not teleport across planes unless a direct link to the caster exists at the time.
