*prod, prod* It's been over a week since you last posted... How is the TAS going? Have you worked out your route planning woes? Hopefully future chapters will be easier to work on than this one.
I very much agree with this post.
Forget party hats, Christmas tree hats all the way man.
Perhaps, but is it faster to let her die than to move her one space to the right? That way, Natasha doesn't die, and Artur doesn't need to counter anyone.
I'm not sure how useful it is to recruit Dozla for that chapter. Based on stats, Vanessa is perfectly capable of dealing with the last two enemies with enough luck manipulation. Then again, that recruitment did get rid of one "Other Phase" message. Based on this chapter, I'm assuming you don't plan to train Vanessa. As long as she is powerful enough to kill an armor knight in Hamill Canyon with a javelin (she probably is) and you have a different plan to kill Fomortiis quickly, that seems to be fine.
Honestly, I'm not sure how feasible Vanessa with Vidofnir is. Vanessa has 73 lance exp at the beginning of this chapter, gains 40 on promotion, and needs a total of 251 for an S rank. A double pierce with one critical would still do it (but would be hell without leveling up Vanessa). Molotov's run used Myrrh, which is still a possibility if you don't mind watching her level up several times.
Those calculations seem right, until you notice that Demon Light gives +10 defense (among other stats). Myrrh would need 12 more strength for a OHKO. If you plan to attack twice, Seth+Myrrh will certainly be able to do it at her base stats, as long as Seth gains 3 points of speed and 1 point of strength between now and then (which should happen even if you don't manipulate his stats). I calculated earlier, and a double pierce with one critical would kill Fomortiis. You'd need 20 strength, and the probability would be extremely low without a high level. The triangle attack would give you a free critical, which certainly won't hurt, but the probability of success would still be fairly low. EDIT: I checked the 1-turn victory in Hamill Canyon. I'll assume that double criticals are impossible to manipulate, since the RNG usually isn't that cooperative. Vanessa needs about 2 additional points of strength to kill the armor knight, depending on stats. If necessary, Vanessa can use Ewan's energy ring, but the kills from chapter 12 should probably be enough. Seth would need 3 additional points of strength to kill Aias with a javelin, but it turns out that Saleh can kill him with Thunder at base stats.
Even if Vanessa doesn't level up at all, there's a heavy lance floating around. I shouldn't have any issues.
