Grats Kalros!

As tempting as it may be, if any of you are struggling with completing the timed run, do absolutely everything to cut any time out of the run.

At least until I got into a rhythm and started ending up with tons of time at the end, I would avoid all looting (except bosses where you had time to), avoid time spent eating/drinking unless you really need to, try to get ahead of the game when able to (such as not waiting for Arthas inside the inn before running ahead and preparing for the next fight), as soon as the 3rd boss drops inside the inn talk to Arthas immediately to at least start him walking towards the bookshelf. One habit I picked up too is after the first boss, I wait in the tunnel on the east side so that I can run either north or south very quickly as soon as the next wave is announced to keep my running to a minimum.

You should try to be a little cautious on the gauntlet, since the elites and trios of mages are not stationary and may jump you while still in the middle of a fight. Keep an eye out for them coming at you and at least try to pull agg with the tank first before a stray chain lightning or heal makes them choose a target you don't want.
