Greetings Tenno, Please note, that because of issues regarding exploitative economy trading between migrated accounts, we have had to make some changes to migration allowances. Sorry for the surprise! The additional list of currently restricted items now includes: Rivens (All types: Melee, Rifle, Shotgun, and Pistol) Arcanes (only ones dropped by Eidolons) Acolyte Mods Legendary Core Primed Chamber As part of this process, account items which are on this list that have already been migrated will be removed, retroactively. We are very conscientious of the new player experience for our brand-new community, and as such, we wish to keep everyone on a fair and even setting, while still allowing our migrating community to enjoy the time they have put into Warframe. We appreciate your patience during this period, and we will be posting updates as developments occur.
