Frequently asked questions
What is the limited spark?
A guaranteed claim of the target limited 6-star after 300 pulls on the banner.
Do contracts carry over?
Spare Data Contracts convert after the banner ends; the spark itself is banner-specific.
How much Orundum per pull?
Pull cost is Orundum-based; enter your pulls on hand and the tool estimates the shortfall.
Is the spark worth it?
For a must-have limited operator, the 300 spark is the guaranteed ceiling.
