Your published material is what counts for the BLECs,
@Starlight Aurate. The word count, specifically. I measured this one at 4297 words according to the chapter you linked. You've long since filled out the challenges for this round in the meantime!
Everything before has been logged.
The round will end very soon! Challenges will be LOCKED a little over 20 hours from this post. Refer to the Countdown on the first post of this thread to get the exact time.
Four hours from then, first turn actions are due. To see examples of what those actions look like, refer to the first few posts during the Battle 0 demo. An "autobattle" AI is similar, but with a lot of "if the boss is X, do Y" to whatever you feel is appropriate. This is only needed for Front Line players--if you're Support, fire when you think it's useful.
I suspect this first fight will have a lot of questions because no amount of explaining makes up for the system in action, so don't be afraid to ask around, especially those who are familiar with how logging works.
And finally, some alerts:
@Umbramatic,
@DeliriousAbsol, and
@Maneki Make sure you get at least something logged before the round ends! Logging no challenges in a round will force you into Support, and during this fight in particular, if you didn't fill any challenges, then you'd also have 0 points... you won't be able to pull off a Support action at all!
