Lost Ark has received a massive load of new content with the new “Feast with Friends” update. Among them is not only a new class, but also two progression events and a whole lot of UI and quality-of-life adjustments. The trailer gives you an overview.
So you can see directly what the new Reaper specialisation of the Assassin can do. It relies on a mixture of daggers, camouflage and clones to take on the enemy monster hordes. To do so, the Reaper can switch between three different modes that give him bonuses to his stats.
There are also two events: Punika Powerpass and Hyper Express The former runs until 18 January, and you can take part in the latter until 8 February. The main purpose of these events is to prepare you for the new end-game content that will be released in December.
