Late to the party, but…

How well tuned is your printer? This whole print is a torture test with lots of retractions and thin walls. For things to go well you will have needed to dial in flow rate, print temperature, cooling, and retraction. As someone else said, if the nozzle catches on an unsupported lever arm (aka one of the vertical pieces before a horizontal bridge has been completed) it can/will break it off.

If your printer has never pulled off this type of print before I suggest running through some basic tuning tests before worrying about potentially wet filament unless you live in a very humid environment. I live in a temperate climate where it doesn’t generally get that humid. My printer and filament live in my basement, which has a dehumidifier in it. I’ve never dried a role of filament and I leave spools unfinished for 6+ months. That’s not to say that you never should dry your filament or that doing so won’t improve print quality. I’m just trying to say that I have not experienced a higher rate of print failure with older spools.
