Hi again, one more update to this thread following an additional query.
Q: If a Scythe is reapgrowing in a Fort, do they need to go out of their way to physically inspect & reap every single cube on their chosen branch, or can they skip corner cubes/stuff with nothing to add and let those weight 0 cubes be SCed later as-is?
A: On the one hand, it is up to you if you want to add your Scythe weight to a Fort cube that doesn't actually need anything done to it. As long as the branch is extending properly and you aren't mistakenly skipping cubes that do actually need stuff added, there is no problem reapgrowing that way. On the other hand, though, please treat tiny cubes with the same due diligence that you would give any other cube; if you're familiar with Mystic gameplay, think about how MSTY technically looks at every new cube spawned. Bear in mind that if you concentrate too much on just extending the main body of a branch, you may miss something, and the Scythe eventually completing the branch will have stuff they have to reap for you.
If you confirm through Inspect that there's really nothing to add, it's still up to you whether you hit the "Reap" button for fun, but as far as the GMs know the only absolute benefit to reaping every single Fort cube is that it may help various player-added scripts correctly calculate how much is left to do. Though maybe those scripts are only calculating available cubes to SC. The point is, as far as HQ's concerned, we care more about you looking closely at all your reapgrown cubes, and less about whether the entire cell turns the "Scythe" color before being SCed.
We hope this resolves any lingering confusion!
