There are 84 pullable void legos. 15x means if you pull a lego you'd have a 15/99 chance for it to be the boosted champ. Figure it takes roughly 200 voids per lego, and you'd statistically average 1200 void shards to get her

(slightly less than that because the boost multiplier goes up after your first and 2nd lego pulls, but I don't care enough to work out the math. call it somewhere around 1k shards ballpark)

Yeah, I learned this issue the HARD way. This was even back in 2021 when we had LESS void legends and I had a lot of free income. 

There was an event boost to get Cardiel. I think at that time, the boost never got higher than a standard10x. Well, I REALLY wanted him for my account. I had something like 40 or 50 void shards at the time so I went into the store to buy more.

At first, I only spent $300. After opening them all and not getting him, I spent another $300 for more shards. After THAT didn't get me him, I spent my last $200 because I felt like I had to be close. Well... I didn't get him.

When I looked at what I did a few days later, I kinda realized what a terrible decision I had made. Pretty much after that event, I did the math and saw how bad the odds REALLY were at a 1% legend drop rate. Over the past 5 years, I have every only got the offered champ twice; Odin and Wixwell. To me, BOTH of them were a pure miracle with no REAL hope of getting them. I just so happened to be opening shards for an event where I needed champs.

The only thing I was lucky with was getting Taras. I just can’t remember how many Void Shards I spent.I was drawn 2x Void shards, not 10x or 15x. 

Progressives so bad still.  Maybe someday theyll actually buff chances like they mentioned.
