However, there is nothing more panic inducing in Dota than getting dust popped on you just as you thought you got away for the first time. ( Also for other heroes but for Riki it's amplified)
I got dusted like 3 or 4 times in that game and didn't die once to it. That's why you buy a diffusal. All my deaths were from yolo diving towers and/or fountain because I thought I was invincible.
