Choose the right version

This release covers the 12 Expeditions, 6 Transcendence dungeons and 4 Sanctuaries listed in the reviewed Korean mode indexes. Deltras has two sections for its phases; section counts are not unique-boss counts. Older four/eight-player videos are clearly marked, alongside current five/ten-player rules. Source dates and difficulty remain visible in each guide.

Field bosses & Nightmare

These guides cover instanced group encounters. Field bosses use the in-game Map → Exploration → Field Named list for location, spawn time and rewards. Nightmare is a separate solo boss challenge with its own stages and entries; it is not covered by the raid tactics above.
