A change is being made in the binding status for some cosmetic pets, and the Osgiliath Steed, in order to allow these items to become Disenchantable into Figments of Splendor when Update 23 is released.

All cosmetic pet items, and the Osgiliath Steed that drop from Gorgoroth lootboxes (and are listed on the Keeper of Mysteries), will become Bound to Account. This will affects items already in-game that are currently trade-able, so players should get these items to the account they want it to remain on before Update 23. This includes the following:

Osgiliath Steed
Tome of the Agarnaith Wormling
Tome of the Ash Frog
Tome of the Banded Snake
Tome of the Blight Frog
Tome of the Diamondback Snake
Tome of the Eager Beaver
Tome of the Lasgalen Owl
Tome of the Little Goat Kid
Tome of the Plateau Mole-rat
Tome of the Red Snake
Tome of the Russet Hedgehog
Tome of the Storm-cloud
Tome of the Striped Snake
Tome of the White Peacock
Tome of the White Peahen
Tome of the Yellow Snake
Tome of the Agarnaith Crawler
Tome of the Gorgoroth Crawler
