New Bloody Treasures in Dota 2: How to get and what are they for?

I’ve recently noticed the “New Bloody Treasures” in Dota 2, but I’m struggling to figure out how to obtain them and what purpose they actually serve in the game. It’s a bit overwhelming with all the updates, and I feel lost navigating through these changes. I really need help understanding this new feature and how it impacts the gameplay. Any insights or guidance would be greatly appreciated.
