School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Duration: 1 day* / caster level ; * - Higher spell slots increase the unit of time used for the duration; see below

The caster affixes a single target object of Small size or smaller in time for the duration of the spell. Momentum, thermal energy, electrical potential, etc are all preserved as well. The item cannot be moved or otherwise interacted with. It behaves as though an indestructible, immovable rod. At the time of casting, the caster determines a trigger that will end the spell early. It can be simple something like a password or gesture, or it could be as complex as a specific person attempting to interact with the object at just the right time in history (think Excalibur in the stone). It can be used to secure one's belongings for a duration, like a temporal lock box, or to set up a parameter trap to guard a sleeping camp, to preserve some perishable or other package until just the right recipient comes to claim it, etc. Arrows in flight, bombs mid-explosion, or other such items can be frozen with this spell such that their destructive energy is released upon trigger, making an effective trap. The trigger can be set to activate out to a distance of 15 feet from the object. A successful Dispel Magic, or similar spell, cast by a spellcaster of higher level than the caster was at time of casting can also terminate the effect.

The material component necessary is a tiny ornate hourglass worth at least 50 gp, which must be irrecoverably smashed at the time of casting.

At Higher Levels:
For every 2 spell slot levels higher than normal used to cast this spell, the maximum size of the object affected is increased by one size category, up to a maximum of Huge, while simultaneously, every 3 levels of spell slot used to cast above normal increases the time units of duration by one category.
2nd level spell slot - Maximum target size of Small, for 1 day per caster level
4th level spell slot - Maximum target size of Medium, for 1 day per caster level
5th level spell slot - Maximum target size of Medium, for 1 week per caster level
6th level spell slot - Maximum target size of Large, for 1 week per caster level
8th level spell slot - Maximum target size of Huge, for 1 month per caster level

Additionally, spell slot levels may be increased to extend the duration. For every level increase that isn't used for increasing target size category, duration units of time go up one category:
+1 spell slot level - Days to Weeks, Weeks to Months, Months to Years, and finally to a maximum of Years to Decades.

This scaling may be used in conjunction with the size scaling, but each portion of the spell slot's level will only apply to one or the other.  For example, a 6th level spell slot may either be used to affect a Large object for 1 week per caster level (2 levels to cast the spell, 4 levels applied to size only), to affect a Medium object for 1 month per caster level (2 levels to cast the spell, 3 levels applied to size, 1 to duration), or to affect a Small object for 1 decade per caster level (2 levels to cast the spell, 4 levels applied to duration only), etc.

This spell is an original work.
