How much protection does fgo have?

GO currently has no guarantee mechanism. Activities are limited to card pools. On the premise of increasing the card drawing rate, the shipping probability of five-star Ling Ying is 0.8%, that of four-star Ling Ying is 1.5%, that of five-star event ceremony is 2.8%, and that of four-star event ceremony is 4.0%. There is no guarantee mechanism, which means that under extreme non-chieftain conditions, there may be 65,438+0,000 sacred spar without splash, or five-star elf gods may be produced by a single lottery. However, a year later, the national service should actually install a safeguard mechanism. If I remember correctly, it should be that 900 sacred spar must be delivered.
