Major Creation
Normally The Path of Conjuring is restricted to items the size of the thaumaturge, both in size and weight. However, by the application of this ritual, the conjurer is able to create items that exceed this normal limit. Tremere magi can surprise enemies by creating a motorcycle "out of thin air" for an escape or anything else they can think up. This ritual requires the caster to sever his own thumb, which disappears during any conjuration. Many thaumaturges suspect that the thumb provides the additional mass for large conjured objects, even though the object may be several times the caster's size.
System: After preparing this ritual, the number of successes on the activation roll determines the multiplier that the conjurer can exceed his normal weight and size limit. (sic) Example, if the conjurer's player earned three successes on the ritual roll, he could create something that was three times his size. Use of this ritual costs an additional three blood points, in addition to the normal costs of conjuring an item. What the thaumaturge creates is still limited by the Path of Conjuring power being activated. Additionally, severing one's own thumb requires a successful Willpower roll or the expenditure of a Willpower point.
