What it is
An event slot in the regular rotation letting you pick specific missions or rewards to focus on — check the in-game task list when it opens since the exact missions vary by cycle.
Prep checklist
- Check the mission list as soon as it opens so you can plan your day around it
- Pick missions that match resources you already have queued up
Teaching point for new members
Custom Selection lets you pick your own missions for the day — check what's on offer and pick ones you can realistically finish with what you've already got going.
