Hi friends,
Currently, if you pick Blitzcrank in a bot game, you can easily get guaranteed first blood. For anyone who doesn't know how bot games work, the bots sit at the fountain inactive until the first minion spawn wave in which they go to their respective lanes. As Blitzcrank you can rush to the fountain at the beginning of the game by flashing over one of the walls. You can then pull one of the enemy bots off the fountain (be careful! It is very easily to accidentally step on the fountain and die) and attack them, getting first blood. They will not respond as they are inactive until the 1:30 mark. Happy hunting.
