With this spell, several wizards can combine their magical abilities and powers to create greater spells. If several casters want to combine their efforts, they must first decide who will be the head weaver. This person is the centre of the spell: without him, the entire spell structure collapses. Also, if he loses concentration all the efforts are lost and the spells as well. Next, they must decide which spell they are going to create. To create this spell, they may use several different or all the same spells of weaker levels which, combined, give the desired spell. These spells must in some way be related to the desired spell. The DM should rule what spells can be combined.
To participate, all members of a "spellcloth" must roll their chance to learn spells: if they miss it, they lose the spell and their effort isn't counted into the whole of the spell. If the head weaver misses his roll, he made a mistake in the weaving of the spells into the new one and everything is lost.
To calculate how much energy is created, take the number of mages involved (specialists count as 11/2 if they cast a spell within their specialty but as 1/2 if not) and divide this number by the total number of mages involved (specialist now count as one). If the resulting figure is larger than 11/4, make it equal to that number. Multiply this number by the total number of spell levels involved (i.e.: add all levels of the individual spells). Now add 2 to this number and round down. If the energy created by the cloth is not enough to form the desired spell, the next spell in line is created instead.
The experience level at which the spell is cast is the head weaver's level plus half the level of every other wizard involved. If this is lower than the minimum needed to cast the final spell then the spell is still cast, but at the casting level of this imaginary lower level wizard.
Because spell weaving takes a lot of time, spellweavers always lose initiative. Also, the weavers cannot be separated by more than 10 feet, and no barriers may be between any individual and the head caster. The number of mages involved is also limited: 11 for a master weaving. Minor weavers only count as _ if included in master weaving, while major weavers count as _, for the purpose of calculating the maximum number of mages.
Master weaving can take any 9th-level spell or lower to weave successfully (the desired spell can be of tenth level).
