Mistward Warfists (Acquisition)
The Devastation part is only the prerequisite to start the collection for the Mistward Warfists (from the page you linked: “Prerequisite: Completion of the Devastation revenant specialization”). The Shatterer, and all the other events/activities, are required to complete the collection. https://wiki.guildwars2.com/wiki/Mistward_Warfists_%28achievement%29
In-game you’re reading the wrong item. The warfists you obtain by completing a collection, which is unlocked as noted on the page you linked. What you read in-game is probably https://wiki.guildwars2.com/wiki/Mistward_Gloves_Plate , an item IN the collection itself. The gloves plate DOES require defeating shatterer.
So… technically, you’re both right. You cant get them without finishing that specialization (to unlock the collection) AND you cant get them without defeating Shatterer (to obtain an item in the collection).
Wow, thanks for the speedy replies
and I understand now..
