PSA: Game mechanics of the Chapter 700 battle
There have been a lot of questions about the mechanics of the battle. Hazō wasn't on the field, or even able to SEE the field, so there's no particular reason we should disclose them. On the other hand, y'all have been asking us to be more open and share more, and it's a good thought. In that spirit, here's what happened:
We spent a lot of time debating various factors, including whether or not the assault force would be spotted on the way in. We rolled for that and determined that no, they were not. Therefore, you were going to have the advantage of surprise.
The next question was how effective the RER bombardment would be against Akatsuki's fortress. After some debate, the answer was "extremely effective." Specifically, it would utterly demolish the fortress except for a few heavily reinforced areas that were intended for seal research/production and therefore reinforced out the wazoo.
Next question: which Akatsuki members should be onsite and which, if any, of them would be in a position to be hit by the RER barrage? There were several scenarios that seemed equally plausible, so the discussion took a while. Eventually, we converged on the idea that, after the RER bombardment, only Deidara would be involved in the battle. (Yes, we are being intentionally cagey about whether there were other Akatsuki members onsite. Hopefully no one will be upset if we maintain
some semblance of a DM screen.)
We looked at what Deidara's plausible abilities would be and we looked at the absolutely overwhelming force and the excellent tactical doctrine y'all had assembled and we said, "Yeah, no, this is a wipe." As such, we didn't bother rolling anything further. We simply said: you win, he loses. Done.
PS: When asked in Discord whether we had used the combat simulator, EJ said that no, we had modeled this 'old school'. In his literal genie fashion, it should be noted that authorial fiat is the oldest school of narrative battlefield resolution there is.
