This spell is a more highly powered detect magic. It allows a wizard to trace magic even if the magic only passed through the area of effect - even if this happened quite some time ago: up to one hour in the past per level of the caster. It collects the impact of magic on the time-space continuum and amplifies it for the wizard to be able to identify different traces of different items - up to two different item or spell effects per level of the caster. It detects the different strengths, numbers, schools, time of creation (up to 1 hour exact) and source and name (wizard, priest, natural) of the magic (spell or item). Note that it does not identify psionics. This spell is able to detect invisible objects or creatures.
The material component is any kind of permanent magic item: even a stone with a continual light or magic mouth spell on it is enough for this spell. If an artifacts is used for this purpose, it is not destroyed but sent to another plane (preferably where it can be used against the characters).
