I think this Hedge Magic spell rocks.

Clone-5th circle, Illusion
The clone spell creates an exact clone of the caster. Upon casting, the caster must enter a state of deep meditation. During this state, the caster may act through the clone, performing any actions that he or she is normally capable of, even casting spells, using abilities etc. The only difference between the caster and the clone is that the clone has one third as many maximum health points as the caster (round up). For example, a theurgist with 32 health points could create an 11 health point clone. Furthermore, if the clone is reduced to 0 health points, it immediately crumbles to dust. Likewise, the clone dissolves at the end of the spell’s duration, or at any time the caster’s meditation is broken (willpower check to resist).

The clone spell does not replicate the caster’s equipment. Thus, any equipment the clone carries must be supplied by the caster. This equipment does not dissolve upon the clone’s death.

The material requirement of a clone spell is an amount of clay, equal in weight to the caster to be cloned.

Note: The nature of the clone is not revealed by sense magic, nor may it be dispelled.
