These are spells derived from combining at least two of the Eight Symbols and are commonly known as Formations. They are all trigger spells in nature. All combination spells need to be balanced with respect to Yin-Yang. That is, both Yin and Yang aspects have to be present in a combination spell but it can be skewed towards either the Yang or the Yin. Depending on the spell’s purpose, Symbols are arranged* according to either the Creation/Destruction Cycle of Wu Xing or the Heavenly/Earth formations. The strongest combination spells are ones that combine all Eight Symbols, followed by ones that combine Five Symbols that belong to each of the Wu Xing elements.For all other combinations, it does not necessarily follow that spells utilising more of the Eight Symbols would be more powerful. Complexity of the combination spell is directly in proportion to the number of Symbols used to weave it but this does not hold for its power.
Some samples of Combination Spells:
1) The Formation of Ba Gua: This is a combination spell built on the basis of all of the Eight Symbols, with each of Symbols being arranged in accordance with either the Heavenly or Earth formation depending on its purpose. The Heaven Symbol is represented by a common pebble containing no traces of the Symbols if the formation is entirely powered by reservoir items. In addition, the casting of this particular spell is tied to specific times of the year. Depending on the purpose of the spell, these times change. This formation is a all-rounded spell and can be utilised for a variety of purposes such as to entrap but not harm,
for attack/defence as well as others (up to GM discretion).
2) The Formation of Wu Xing: This is built from five Symbols that correspond to each of the Five Elements (Wu Xing). Another all-rounded spell that makes up for its relative weakness when compared with the Formation of Bagua by not having the limitation of being tied to particular times of the year. In addition, this particular formation has the advantage of being self-perpetuating to an extent if arranged according to the Creation Cycle.
3) The Formation of Three Stars: An offensive spell maintained by three mages drawing on a distinct Symbol or if powered entirely by reservoir items, is composed of three sub-formations based on a single Symbol.
4)The Formation of Six Harmonies: Drawing on the six Symbols besides Heaven and Earth, this spell is a powerful cleanser of all negative effects in an area, including plague and evil influences.

This is a system of magic evolved from Tuner Wizardry. Practitioners (known as Geomancers) work solely with enchanted items containing elements of the Eight Symbols. In terms of combination spells, Geomancers set them up to be in accordance with the Bagua (an octagonal instrument used by these Geomancers), which designates a range of alternative formations that each of the Eight Symbols need to be arranged in to achieve a particular purpose.
