This powerful spell was researched by the Lord of Telnorne. It is actually used to create a magical rod (3 feet long and 1 inch in diameter) that projects a continual zone of increased magical potential in a spherical area of effect equal to a radius of 1 yard per level, extended outward from the rod in all directions. This spherical zone makes magic function at its utmost effectiveness, normally. But, it can be used to travel to planes with reduced magical factor ratings (MF) while keeping an MF rating of 0 within the area of effect. On planes with an increased MF the spell simply allows all spells of ninth level or less to work optimally. The zone will permeate any area which is not totally enclosed in a lead casing or protected by an anti-magic shell which withstands the dweomer.
All anti-magic shells or effects that come within the zone react as if a dispel magic is cast upon them each and every round. Every round the two areas interact the anti-magic zones have a chance of dispelling as though a wizard of four levels higher than the wizard were trying to dispel magic against them. On planes with a negative MF rating, everything within the area of effect operates as though the MF rating were 0. So, someone with a ring of flying could fly within the zone, but exiting it would cause them to drop like a rock! On a negative MF rating plane, anti-magic shells are dispelled at the normal level of mastery or the wizard and all spells cast by any class of characters, whether native to the plane or not, operate at a normal MF rating of 0.
The spell's duration (from activation of the rod) is equal to a base 1 day per level in a prime material plane with a MF rating of 0. On negative MF rating planes, the duration is calculate as the total number of whole days left for the rod to operate divided by the result of the MF rating multiplied by -1. For example, a 20th-level wizard activates the rod and hurriedly enters a gateway to an alternate prime material plane with a MF rating of -5 (since the spell must be initially cast on a plane with a MF rating of 0 or better). The duration would be determined thus: 20/(-5?-1) = 4 days. But, if the wizard had operated the rod (for more than 1 turn) before entering the gateway it would have lost a day's duration and be calculated as: 19/(-5?-1) = 3.8 days = 91.2 hours = 547.2 turns = 5,472 rounds. If the wielder had travelled to a plane with a MF rating greater than 0 the spell's duration would be calculated as the base duration multiplied by the MF rating of the plane.
Whenever the rod changes alternate prime material planes (even if they both contain the same MF rating) its duration is recalculated with the current remaining days of operation left used as the base for determining the duration of the spell (disregard any remaining duration that does not equal a day or more in length). If the rod travels from a positive MF rating plane to a negative MF rating plane the rod is totally disrupted in the transferral as though the spell had ended, and vice versa. Dispelling magics will only affect the rod for one single round unless they are cast by a demi-power, lesser power, or greater power, in which case a successful dispel magic will cause the device to become disrupted as described below.
The rod is the only material component of this spell. It is made from the purest mithril and rune inscribing agents (costing at least 7000 gp). Then, 9 deep blue amethysts (1000 gp each) are inset to the side of the rod among the various runes of power, and a large sapphire (1000 gp) is affixed to the top. Once the rod has been fashioned (2 months creation time minus 1 day per level of wizard working on the inscribing of the runes down to a minimum of 1 month) this spell can be cast upon it, empowering the rod with enormous magical potential. From this point, the rod remains dormant until its power is activated by speaking the proper command word and willing the rod to function. Until the rod is activated the casting wizard loses a single 9th-level spell casting slot because of the bond that he has established with the rod's dormant power. While this spell could be inscribed onto a scroll it would still require the rod as a material component and the wizard who inscribed the spell would not regain the spell slot until the potential of the scroll was released through copying it into a spellbook or casting it onto the rod and activating the rod (note: an apprentice may be used to inscribe the runes upon the rod freeing the learned master to further research).
Although almost any sentient creature may utilise the rod, in the hands of the original wizard it will convey a personal magic resistance equal to his level of experience (and cumulative to any other magic resistance he may be employing). On any prime material plane the rod will also act as a rod of striking, conveying a magical +3 to-hit bonus and striking for 3d6+3 points of damage per round. The rod may only strike once in any melee round no matter if the creature wielding it is capable of multiple attacks with weapons. During the last turn of the spell's duration the rod will begin to hum extremely loudly (hearable in a 1/2 mile radius. During the last round of the spell's duration the rod will glow with extremely powerful magical electricity, causing 1d20 HP of damage to all that touch it, per tenth of a round of contact. In the last round is will flash with a bright light (causing all in the zone to save versus rod, staff or wand, or be blinded for 1d20 rounds) and then cease to function. This last burst of energy transmutes the mithril rod into pure lead, causes the runes to dissolve, and transforms the 10 gems into a useless powder.
