Oh I completely forgot! Yes, you are correct. @Ribombee, you can save the slaves in 13x. That Monk will kill a slave each turn (except Sythe), starting on turn 1. There are at least three ways to stop it though: having a unit of yours with ranged magic or a long bow, if you gave a Boots to certain units, they would have enough Movement to get to the Monk, or using the Bard to refresh a unit to get there.
I think there is actually a reward for saving them all. I believe that’s how you get your second Reveal Gem. Thanks for chiming in, @Violentvito
This is one of the harder/more obscure “mini-quests” in the game, so don’t feel too obligated to complete it. The desert items that this Reveal Gem reveals (in Ch 21) are cool, but they’re not paramount to a playthrough.
Thanks for the message! Can you send me your .sav? I should be able to investigate it to see what’s triggering that game over flag. Worst case scenario, there are a few ways to resolve it even if we can’t deduce the exact trigger. Rigas had this issue, but we were able to get past it. So, not to worry.
