There seem to be collectibles that drop ONLY in the missions. I haven’t seen any in Eastern Wastes though. I suspect if you haven’t seen a set, it is from the mission. Note: When the boss mobs in the missions are beat, all of the corpses poof and the collectibles are no longer lootable. This isn’t a problem in Great Divide where most of the collectibles come from the wolves you kill during the mission, but it makes drops during the Velks mission quite annoying to collect.
Need to put things in the chest. Or move them somewhere else, maybe add some trash to the missions, which needs to be cleared first. Something like 20-30 trash mobs.
Kael is full of trash mobs. They drop the collects from static Kael. ONLY the event mobs drop collection items, for that set.
KD exp also seems in line with KD 18 years ago would do arena and plate cycle for hours for next to no exp.
