I used the Burden of Eternity to make the 496 ring token a 535 timeless ring. This would be an upgrade to a 530 ring, but I noticed that the secondary stats appear to be severely lacking.
For an easy comparison, I'll put it against a 530 socketless ring, Durumu's Captive Eyeball.
Amaranthine Signet of the Savant (535) vs Ring of Shamuru (530) respectively:
1471 to 1403 stamina
980 to 936 intellect
969 mastery to 678 spirit and 532 critical strike
Ignoring the 68 stamina, the 5 item levels allow me to gain 44 intellect to sacrifice 241 secondary stats.
