Hey Sega, starting a playthrough again after a few months, and I don't know if it was changed and I didn't see it in the notes, but the fort condor teleport NPC isn't showing up hardly at all. I just did the 5th FC battle and he only showed up for 2 and 3 in Junon, then I backtracked for the 5th and found the NPC still in Junon. For the 6th he was not in Cosmo Canyon, or Junon so I had to fully backtrack. Also, I don't think I ever got the answer, but how much stat points do Barrets innate stacks give per stack?
Edit: *Sigh* Ok well I completely forgot about the NPC popping out of the sealed door, too bad it was after I already backtracked hehe. Remembering when battles become available in vanilla is causing me grief it seems, however the issue with the 4th battle NPC being in junon when the team is near gold saucer still stands.
I think the NPC spawn times are:
1: No spawn (first physical visit to FC)
2 & 3: Junon, before and after getting into the water
4: After getting buggy, no spawn as players usually backtrack to Junon continent with buggy for sleeping man access + enemy skills, but I think he spawns in Gongaga on one of the paths outside the town just in case (and for later after Temple of the Ancients when party relocates to Gongaga)
5: Cosmo Canyon after selecting Cave of the Gi party, NPC appears when door opens
6: After completing Cave of the Gi, player can reuse the NPC in Cosmo Canyon
7: Rocket Town, NPC is in Cid's house sitting in the green car
8, 9, 10, 11: The Bronco is available at this point, making it easier to access either NPC spawn locations or Fort Condor itself so no new spawn locations were made
12 & 13: Forgotten City, spawns inside shell hut to make this fight accessible; can be used again after boss fight to save a return trip
14-18: These are problematic because the game 'skips' over them during the Junon Raid scenes. I decided to leave these inaccessible and started Fort Condor off with enough funds to cover these battles.
19: Highwind now available
20: Inaccessible, happens during Mideel collapse (placing a teleport here would have been funny, but maybe a bit inappropriate for a story-critical scene)
And that's all of them. The 4th spawns in Gongaga and can be used if players don't want to go back to the Junon continent with the buggy. It can also be used for quick access after Temple of the Ancients is finished (and before sleeping forest is woken up).
