How to think about choosing it
Consider it when the selected weapons can use longer effect duration. This is selection guidance inferred from the verified effect; it does not mean the item is the first priority for every weapon or build.
When the evolution is the goal, reserve a passive-item slot for Spellbinder. When the effect itself is the goal, compare whether the main weapons in the current run can use that stat.
Requirements for Unholy Vespers
- Raise King Bible to level 8.
- Hold Spellbinder at level 1 or higher.
- After meeting both conditions, open a chest that can produce an evolution.
Not every chest is guaranteed to evolve a weapon. On many early normal stages, a chest from a boss that appears at or after 10 minutes is the practical starting point, but stage-specific exceptions exist.
If the evolution does not appear
- Confirm that King Bible is level 8.
- Confirm that Spellbinder is in the passive-item slots.
- Check that it has not been confused with another evolution material.
- Check whether the chest could produce an evolution under that stage's conditions.
