First one I have found and on a tiny world. Seen multiples of every other civ.
yeah they do seem fairly rare. of all the planets i’ve scanned, only once did i find NATIVE syntis, but i’ve found buttloads of giants/squids/humans/PR/kitties. The syntis i have found are from player restart’s so i’m not counting those as “NATIVE”.
Pretty sure it’s because the temperature range is such a rarity. Native syntis pops need to be in the ±10C range to have a chance of spawning. Most planets aren’t gonna be in that range based on my exploration. So it just makes them rare. Mountain Giants have a similar setup but they have entire planetary systems that spawn them pretty much guaranteed (unless a home world wound up there instead) and that makes it even MORE difficult for you to find Syntis.
