[2022] Only possible to get Arkesia Paper Hat Chest by watching one channel

The paper hat chest is one of the rewards from the Legends of Lost Ark campaign: Legends of Lost Ark - News | Lost Ark - Free to Play MMO Action RPG

Though most streamers are on T4 now, these earlier rewards will make their way back around so that folks can obtain anything they may have missed before the LoLA event ends!
