I really love Crystal Maidens shard... did you know:

Basic patch change, but your clone now gets destroyed by your ult and level 2 Crystal Nova. So you can trigger it whenever you want, clearing waves and jungle camps faster and more easily. Which also means you can put more early points into the Arcane Aura! https://streamable.com/d2stkn

It can be cast during your ultimate. Your Aghanim's Scepter Frostbites everyone standing in your Ult for 2.5 secs... but how about instantly Frostbiting everyone? https://streamable.com/2zg8ro

It disjoints projectiles. Enemy only has projectile interrupts for your ultimate? Ooops... https://streamable.com/pr2ngn

It blocks Pudge hook LOL take that https://streamable.com/3e42q1

Your normal Frostbite has 6 sec CD and disables for 3 seconds... So with Shard you have your very own 9 sec chain disable! (almost, if it weren't for the 0.3 sec cast time of Frostbite) https://streamable.com/9928ap

And I mean of course, you can go over cliffs, but everyone knows that, I just had the video lying around https://streamable.com/mal4vr
