Single pull vs multi pull

is there any difference? i know it sounds like a silly question since obviously more attempt equal better chance at pulling rare stuff but several games have stuff like “increased rarity if you pull in bulk” and i was wondering if this was the same, cause the only time when i pulled something above ultra-rare rarity was when i decided to open 22 glory chest all at once

There is no difference. Many games employ something like higher changes on the multi pull, however not this one.

As Machiknight says, although if you’re purchasing gem and event keys then there is a bulk discount.

Edit: Improved clarity per @yonizaf’s suggestion below.

You mean there’s a bulk discount for gem keys. For gold and glory keys there is no discount as far as I know.

Yes, I was thinking about gem and event keys. I have edited for clarity.
