They need to open the Mabar stuff and update it to be useful. I really like the Cloak of Night. At ML24 it comes with DR 15/Good, Dodge +18%, Ghostly (10% incorp miss), Invisibility Guard (high proc rate, 50% conceal miss), Deathblock, & Nightmare Guard (useless due to dc 22 negs). Wiki also says it can come with Mythic +3 to PRR/MRR but you probably have to farm a dozen of them, thus a thousand ingredients, to get one.
But most of the rest of the stuff is junk outside of the +5 Tome (limit one per character).
