[I'm putting this under exploits cause I highly doubt blizzard wants you to be able to teleport in the air to take no damage]
Allo, I dont think this has been posted before, and I know its known by alot of people, but there are some people who dont know, so here goes.
If your a mage, and you want to jump of sper high places without taking any damage/very little, all you need to do, is, a little before you hit the ground, you hit blink, AkA Blink jumping, whenu do this, you either:
A: Blink right onto the ground taking no damage (this is when its done perfectly (its really hard ))
B: youll blink up 20 feet in the air, but the thing is, you only take the damage from that 20 feet, not the 2000 or somthing
People who are just doing 1 jump and dontneeda do it over and over again can just use ice block, it has a 5 minute cooldown, but, if u dont think you can blinnk jump and survive, u can just click it and wait to smack the ground for 0 damage.
Hope this helps people who didnt know about it.
