In order to complete these achievements you have to succeed the Warden event (the entire event up on the platforms) without being hit by the Marionette. If you are hit, you don’t get it. If you fail the event, you don’t get it. Stay sharp and break that chain and you’ll have it.
So..in order to get what should be simple achievements, we have to not only complete the event without taking any damage from the Marionette while also dealing with the Champion Boss on our platform, but also rely on the other four groups to not fail their events, otherwise we get no credit what so ever.
…Oh sweet mother of poorly thought out achievements. Welp, guess I’ll be doing the Daily for the LS each day in order to get enough to credit to finish the meta.
