With the downfall of Amdapor Keep after the changes Castrum has taken over as the speed run king, now being the most efficient way to grind out the philo tomes for your Dark Light gear. I decided to make a vid on how to do this effectively and get your runs below 30 mins pretty easily if you have a bit of gear already. I was really surprised at just how much of the dungeon you can skip and a few other little tricks that speed things up by a lot. Best if you are in a premade party but if not you can always try to teach the others! Anyway enjoy and good luck with your Castrum runs!

Also they should really have a separate queue for people speed running and people doing it for the first time in their story mission but I guess that is another story. Plus a way to skip all cut scenes would be nice because there are a lot in this dungeon!
