Fracta Conqueror sits at 25.7% — a late-route calamity by the shape of the curve, in the same band as Dorothy and Melty. Element and week are unknown.
When this happens
Not documented
Boss weeks are the spine of a run. The June fight opens the year, the September fight is the aura deadline, December is the difficulty wall, and week 48 closes DAYS OF TORNADO. Everything between them is feeding and stamina management.
What is not documented
Everything about Fracta beyond the achievement name and its unlock rate is unpublished. That includes the element, the fight window, and the moveset. Sites that print those details are extrapolating from the same fragment we have — the difference is that we label it as missing.
If you have fought Fracta and can describe the encounter, that is exactly the kind of detail this page is waiting for.
