First the thing you need is :
- Genuine Smeevil Courier ( Red Colour should be unlocked )
- Baby Roshan ( If you have a Roshan with an effect, it will add the effect to it. )
- Buy a courier .
- Make sure you equipped the Baby Roshan courier in the player's loadout before activating it .
- Once the courier is activated, equip the genuine smeevil in the player's loadout (http://imgur.com/NmqylRX)
- You may or may not need to upgrade your courier into a flying one
- Congratulations! you now saved thousand of dollars by having a bugged roshan :P
Good Luck and have fun guys :D
