The Chronicles of Anglarthea - The Legend of the Sages Stone
Unguent of Timelessness
A wondrous potion
When applied to any matter that was once alive this ointment allows that substance to resist the passage of time. Each year of actual time affects the substance as if only a day had passed. The coated object gains a +1 resistance bonus on all saving throws. The unguent never wears off, although it can be magically removed (by dispelling the effect, for instance). One flask contains enough material to coat eight Medium or smaller objects. A Large object counts as two Medium objects, and a Huge object counts as two Large objects.
There are some rumors that say this item can also reverse the effects of time, however it’s rather controversial.
The party (Dallamar) found this on the body of the dwarven miners in the last area of the Hammerhore mines. It is currently with the wizard in an unknown area.
