Ideas for Taliyah's ultimate?

So as we all know Taliyah was just teased to us as a new champion and she is an Earthbender! I for one am excited for this, as well as special interactions towards Yasuo, Azir, Nasus, Xerath, Renekton, and Riven. However, since we only have a backstory i, like many other theorycrafters, will start speculating about her, and that's just what i have done here.

Here are some quick ideas i came up with of what taliyah's ultimate could be:

Earthquake - She designates a large area of ground to ripple and pulse with an earthquake, enemies caught inside take damage and bounce around the location for a certain period of time. Debating whether they should be incapacitated or if they should still be allowed to attack just can't move their character around.

Aftershock - She strikes the ground and a circle appears under each enemy champion, after a short delay if they are still inside the circle they take moderate damage and are stunned (knocked up?), if enemies stand in multiple circles they take extra damage but remained stunned for the normal time. This is a global ability. If you ever played HotS it's like Diablo's apocalypse ability. Considering Karthus (and soraka) are the only champions that have a global ability that can affect every enemy/ally champ, I would like to have a 3rd champion that have something like this.

Stone Arena - Consider this a combination of Jarvan's ult and Poppy's W, where she creates a circle (or you know what let's mix things up and make it a square) of floating stones, while inside the stones enemies cannot pass through while allies can enter and exit at will.

Shatter - maybe have her be another resource management champions like Syndra and illaoi where everyone of her abilities create a floating stone at a location and her ult shatters every stone and makes shards fly out in all directions from each stone. can cause a high amount of damage considering how you could tweak range or even if it's more like a projectile.

A cool effect i thought of would be to reverse healing and damage within an area but that doesn't sound earthy, but Rito! Take this in consideration for future champs!
