Watch before moving
Dungeon threats mark their intended space before striking. Treat a floor lane, ring or falling column as a readable warning. The realm’s environmental clock runs while it is occupied, rather than advancing its puzzles while nobody is present.
Find the second objective
Current dungeon layouts combine a seeded route variant with a realm condition. Unlocking a hidden room pacifies its wards. Mastery also requires the sentinel quota to be defeated; leaving actors behind or allowing them to despawn does not count as a kill.
Finish with room in the bag
Ordinary drops, guardian loot and mastery rewards are separate transactions. Review inventory before collecting. A learned blueprint is knowledge, while an unread plan is still a carried item that must be deliberately learned.
