How To Solo Dragon at Level 3 with Nasus

I thought to look around to see what other champs can solo drag.

I figured out a way to solo drag at level 2. I can have the dragon dead by 4:10.

I see you killed it around 5:13 with that method.

As a jungle main , I feel like that minute is very important. I don't feel safe starting dragon after 4 minutes... Much higher chance of the enemy moving through your river / warding, ect. Especially if their team is aware that the champ is capable of solo'ing dragon.
