- Not to be confused with the summoner spell
Dash
Sejuani using 
Arctic Assault.
A dash is a type of champion ability in League of Legends that causes the caster to move to a location or in a direction while traversing the intervening distance. This is distinct from blinks, which describe instantaneous movement from one location to another.
All abilities that involve changing the location of the user via direct transit are classified as dashes, even ones that visually appear to be 'jumps', or utilize movement through the air - the game engine does not take into account the height of a unit so jumping units are considered to be on the ground for the purposes of skillshots and alike.
Most dashes can be used to pass through otherwise impassable terrain, which require their end point to be within walkable terrain for this to be possible, but certain spells (such as 
Lucian's 
Relentless Pursuit) have a small overhead where the crossing will succeed where it otherwise would not if a wall is just slightly too wide for it. Attempts made to cross terrain with a dash that does not fulfill this criteria will simply result in the champion stopping short.
Also, it should be noted that abilities with 
knockdown effects (such as 
Veigar's 
Event Horizon or 
Jinx's 
Flame Chompers!) will stop units mid-dash (unless they were 
displacement immune, 
crowd control immune, protected by 
spell shield, or 
untargetable). 
Airborne effects will also override and effectively interrupt dashes.
Dashes should not be confused with displacements, which are usually sourced from enemies (and are classified as 
crowd control).
