Blink < onlyinclude > < / onlyinclude > Blink is a core mage ability learned at level seven . It is a self - only instant arcane spell that teleports the caster forward 20 yards ( if possible ) and frees the caster from stuns and roots . Notes . The spell negates the effects of " Stun , " and " Root . " This means it does not free the mage from Sleep , Charm , Fear , Snare , and Daze effects . The mage gains a buff called Blink , which lasts for less than a second and makes the caster immune to everything for its duration . Thus , the mage cannot be harmed or re - stunned while Blinking . The teleport is stopped by certain types of terrain , and does not work near indoor - outdoor boundaries . Teleporting across the majority of flat surfaces should allow the caster to reach the full 20 yards ; there have been exceptions found to that rule . Teleporting near a cave entrance will Blink the caster to the very edge of where the cave becomes " outside " . Some bridges are considered indoors and the edges will shorten the Blink distance . However , even if the caster does not go the full 20 yards , he will still be freed from stuns and roots . Tips . During long periods of walking , Blink can effectively shorten the total time of your trip if used every 15 seconds . This is approximately equal to a 20 % run speed increase . Always be mindful of the cooldown : if using Blink would merely look good , hold onto it until later when it may save you a trip to the Graveyard . You can avoid some pointy terrain distance shortening by hopping into the air and blinking mid - jump . Blink uses line of sight to calculate your travel distance . Jumping gets you over small obstacles that would stop you , such as small trees and rocks . If properly timed , Blink can be used to decrease or completely avoid falling damage . Learn what things you can break out of and what you can ' t . By " bonds " it means Root s , not Snare s . For example , you can Blink Entangling Roots or Frost Nova , but not from Chains of Ice or Crippling Poison . Blinking will not spill you over a cliff or out a window , so if your Blink would have you end up over a drop off , you ' ll stop at the edge or - if you ' re at the edge or there is no edge - you won ' t move . There ' s a little trick here : when you ' re in midair ( falling only ; a normal jump is not " midair " ) , this effectively teleports you back up towards where you left solid ground . If cast half a second before impact , you are immune to the falling damage . You can take advantage of this when leaping off very high cliffs and blinking just before you hit the ground . Practice makes perfect ! You ' ll take little to no damage if done right . Jump , spin 180 degrees in mid air , and Blink when being followed by a hostile player . They ' ll lose a few seconds trying to find you if you manage to get behind them . Though it may have limited uses , Blink can also be used to " jump " over the aggro radius of one or more mobs if your level is high enough that the aggro radius is small enough to Blink past . Generally this will only work on green or grey level mobs . When using the mage spell , a player can often be at the whim of momentum . If a Slow Fall is carrying you too far , using Blink while in a Slow Fall will remove all forward momentum and leave you floating straight down . While this can allow some precision , it can also condemn the player if the target is undershot . If being targeted by , for example , another mage ' s , Blinking toward the enemy , to end up behind them , will cancel their spell ( since it requires its target to be in front ) . Avoid blink pulling : Blinking too far ahead might accidentally pull a boss ! Bugs . The line of sight calculations experience severe problems when leaving or entering buildings , caves , and bridges , or even when passing a change in terrain texture . This can result in Blink moving you a much shorter distance than it should , or not moving you at all . This , combined with lag , can make it seem like Blink makes you travel backwards . Not a good situation when you are running away from a rogue .
