Watchful Eyes

The spellcaster must choose easily portable objects to enchant, and must make them identical (within reasonable limits). The objects together undergo an elaborate “curing” process that somewhat resembles the metapsionic method of empowering an item. This takes the spellcaster at least one hour per day for one month. If the spellcaster skips a day the process must start again from scratch.

Each spell enchants up to 100 identical items. The spellcaster must touch each item during casting. A spellcaster who has more than 100 items can cast watchful eyes consecutively, so long as the curing process continues daily.

Any number of spellcasters can attend. When the caster finishes with the final item, the spell activates for all items at once. The items appear unchanged but now detect as magical for the duration of the spell.

Thereafter, those who attended all the castings can select and tune in on any enchanted item up to 100 miles away, as described above. This takes 1d6 rounds. (Note: the clairsentient effect works normally, independent of circumstances: for instance, it works even if the item is concealed. The DM may assign negative modifiers for extreme range, presence of interfering magic, etc.)

The watchful eye carriers become aware of this magical sensing only if they would ordinarily detect magic used in their presence. Detect scrying identifies the item, but nothing can trace the clairsentience back to its source.

This spell requires one other material component: a conventional magical scrying device, such as a crystal ball, which is not expended in the process.

Alliance leaders find the watchful eyes enchantment expensive and time-consuming, but effective. They guard its secret closely, and most other spell-casters have never heard of it. Some monarchs know of the spell, but not the procedure. They would pay a fortune for it.
