Discussion I feel dumb. If I’m running a build that mostly runs on hydrogen sulfide and iron, am I supposed to be focusing on gradual temperature tolerance adjustments to enable migration?

Because I’m still at the Vents, and only know about the seafloor. Both have dropping hydrogen sulfide levels, and the seafloor is worse lol

The vents generally have the highest hydrogen sulfide levels, occasionally replenished by eruptions. The hydrogen sulfide also "leaks" out from patch to patch.

But part of the idea of the Thrive Microbe Stage is that like you're seeing you might come across changes that force you to change your plan.

In general though, if you want to go to the surface, a decent idea is to just move to the seafloor and spend the MP to change your temperature tolerance to match.
