What spell/power/item/mastery allows you to jump the hills?

I was watching a video and saw Warwick doing it?

dashes or blinks.

Example Dashes: Gragas, Nid, Ahri Example Blinks: Flash, Teleport, Ezreal

Dashes can be interrupted by some cc(knock ups, knockdowns, knockbacks) and travel through the space that is between point a(starting point) and point b(target point). Blinks ignore that and just take you from point a and place you at point b, ignoring the space in between.

They also work differently when it comes to terrain. With a dash the skill has to clear the wall completely in order for the champ to go through it, with a blink the skill has to make it at least halfway to go through. So a dash that travels 400 units cannot clear a 500 unit wall(but could clear a 350 unit wall), but a blink that travels 300 units can clear that 500 unit wall, since the distance traveled is above the 250 unit halfway point.

They also react differently to some enemy skills, such as Vigar E and Poppy w(their big circle skills). Both of those skills interrupt dashes and stop them by applying a knock down(basically a .01 second knock up), and doing their second effect(stun in vigar's case, damage in poppy's). Blinks, like flash or Ezreal's e, will ignore these skills and allow the user to continue on their merry way, as they never traveled through the field.

Taliyah's e, her minefield, also detonates on enemy dashes(as well as allied knockbacks and pulls), while doing nothing to those who blink through the field(like a Kassadin ulting for instance)

Thank you to everyone.
