I am under the impression it was changed in December of 1999 to a no mana drain/regen buff, and not December of 2000...the description does not have the year on it, but that would explain me using it in Kedge Keep pre-Kunark...
If you read the comments I believe they are bugged to show the same date: 01/28/01 for some reason...they talk about manastone and stuff, so I believe these comments are from pre-kunark even tho the date on them all seems otherwise.
