Hello Dan, I think the issue would be whether the mind and belief are developed strongly enough to support the working. Tools are no more than aids - though they may become imbued with energy through repeated use or specific charging, they still primarily play a supporting role to the mind of the magician. Evocation can successfully be done while in a simple asana with no more than a circle and triangle of manifestation mentally cast - in which case you are more working in an astral temple than anything else. The issue that arises, as alluded to above, is that concentration might wander and the magician lose control.
