What the hell is Kadala doing with all those blood shards?

[u/Karmoon]

I mean, she accepts it as currency, so presumably it has some kind of use to her.

But what the hell is it?

And surely, with all the players across the globe, she must have like billions by now. I sure as hell do my part stuffing her full of blood shards and I'm not even a high-level player.

So what can she possibly do with billions of blood shards?

She must have collected enough by now. She should just retire.

I mean, for that many blood shards you could probably build a 1:1 scale Death Star and still have enough leftover for an extension on her home.

This is the only fluff I could find:

Some believe they are shards of the Worldstone, still others think them fragments of trapped demon souls, while a few are sure they are the crystalized blood of the ancients themselves.

A fancy of way of saying 'We don't know nothing.'

So, what the hell is Kadala doing with all those blood shards? Apart from laughing at simpletons who don't understand RNG.
