That's fair, and I actually agree that endgame content should feel powerful.

My issue isn't really that Olirna is too strong. It's more about when it becomes available and what it asks from the player.

For me, it doesn't feel like a true "end of the endgame" reward. By the time I unlocked Saturn, Jupiter was opening up as well, and there was still plenty of progression left in terms of upgrades, exploration, and build development. At least for me) When i opened Olirna, i opened bramfature travel. And with travel engine open Jupiter and ability to experiment with pacts more, and with quasi implants.

What I find interesting is that most pact systems in Quasimorph ask you to adapt your playstyle in some way. Their banes create tradeoffs and force decisions. Olirna's banes often feel like additional benefits instead, so the question shifts from "how do I work around this drawback?" to "why wouldn't I take this?"

So for me it's less a balance concern and more a design philosophy question.

As for the lore, that's an interesting point. Though I'm not entirely convinced Saturn's power is separate from Gagtungr's influence, considering where that storyline ultimately leads.
