The timeline for this Abyss Battlefield was 15 days.
15 days was enough to complete the Main Quest and the first two Challenge Tasks.
But the last Challenge Task would be very tight for time.
"Challenge Task 3: Expel the Bloodline Demons from the Black Stone Mine and help the Darkville Black Iron Tribe rebuild their homeland."
Challenge Tasks weren't mandatory.
On the surface, not completing this Challenge Task meant missing out on one Divine Energy reward.
However, if the target was the World Task reward, the situation would be different.
The objectives for World Tasks were not displayed on the task panel, so they could only be guessed through analysis.
World Task objectives all shared one thing in common, which was to change the world structure of the current world.
On this Molten Lava Plain, the world event was the conflict between the Darkville Black Iron Tribe and the Bloodline Demons.
