• Bind more keys on the keyboard to speed up leveling and skilling (that saved me at least 1 sec)

• try double reseting Q on nexus. If timed correctly that can save at least half a second

• similar to double Q on nexus, double smite herald and use eye to finish it. (one auto is quicker than one R)

172 attempts total and I still missclicked and didn't place the dummy to proc lethal tempo... However the perfectly timed double AA cancel kindof made the attack speed factor irrelevant.
