Simply, but efficient way how to a void fall damage (works on 3.0.2) as a druid.
1 - 3 seconds before you hit the ground, cast Rejuvenation [Any Rank] on yourself. and you will get no fall damage. Worked for me 3 times, jumping from Thunderbluff. The point is so you have Green-flashy animation on you when you hit the ground.
Enjoy
