My second attempt reaching the capital at the lowest level I could manage(first attempt: lvl32, second attempt: lvl19) sadly no unique dialogue with perpetua yet and there's not much room for optimization, defeated 1 unnecessary enemy and defeated 1 mandatory at night if anyone has better luck/finds unique dialog I'd love to see it
When you fight her the second time she is level 5, we dont know her level at the capital, but she says on her way home from the capital she hit level 10 and her self identify (somehow) says she has no more room for growth. (Like idk does her exp say max or something?) So she could be anywhere from level 5 to level 9 when she checks your level and is crushed.
