The title of this page and the ability name are misspelled Eldrich Rune, missing the T in Eldritch. I don't know if it used to be incorrect in game or not, but currently this ability is listed in my AA window as "Eldritch Rune" with the description:
"This ability provides Enchanters with an additional line of defense in the form of an added self-only rune. Each rank of this ability provides a stronger rune than the previous."
This ability is an instant cast, so can be used while running. It does not stack with the self-only line of rune spells, but does with the ones that require peridots and with the strength-based Rune line of spells like Uproar. It also stacks with the epic clicky.
It has a reuse timer of 10 minutes. It has a base duration of 36 minutes and can be extended with AA but not with focus effects. There are currently 14 ranks of this AA. The first rank is available at level 61, rank 2 at 63, rank 3 at 65, rank 4 at 66. That's as far as I can confirm.
The Alla spell database contains the information on how much damage they absorb though:
Rank 1 - 500
Rank 2 - 1000
Rank 3 - 1500
Rank 4 - 1800
Rank 5 - 2100
Rank 6 - 2400
Rank 7 - 2700
Rank 8 - 3000
Rank 9 - 3300
Rank 10 - 3600
Rank 11 - 3900
Rank 12 - 4500
Rank 13 - 4900
Rank 14 - 5600
