Fire Catwalk With Me

In case you're not a David Lynch fan, this is a play on the title of the Twin Peaks movie prequel, Fire Walk With Me.

You can not upgrade any mythic item from +0 dungeons anymore into a T-Set at the catalysator to make this achievment done easier. You have to watch out for the rank of the item and the source, as shown in the table below:

Explorer - Item level 415 to 437 - Can NOT be converted into T-Set
Adventurer - Item level 428 to 450 - Can NOT be converted into T-Set

Veteran - Item level 441 to 463 - CAN be converted into LFR Items
Keystone +2 to +8 End of Dungeon Loot

Champion - Item level 454 to 476 - CAN be converted into NORMAL Items
Keystone +9 to +16 End of Dungeon Loot

Hero - Item level 467 to 483 - CAN be converted into HEROIC Items
Keystone +17 to +20 End of Dungeon Loot

Myth - Item level 480 to 489 - CAN be converted into MYTHIC Items
Keystone +16 to +20 Weekly Reward

There seem to be exceptions of Items that can also be converted, such as the Items from the Zidormi Timerifts or world bosses in Zaralekk Cave, some people have mentioned. But I was not yet able to check this/try this out.

I have no idea where the wrists or cloaks drop. I can't find any data. Is this even completable?
