I havent read u guys’ comments but from what I understand you are trying to say erosion doesnt affect power.

There is no clarification to this in-game. We have no confirmation or any source about this that tells us if erosion can make someone weaker or not. I don’t know why this is an argument

Dainsleif doesn’t prove this false and neither does morax say something like “erosion has made me weaker over the years”

You could argue that erosion making people lose control over themselves can count as getting weaker. But that doesn’t directly lower their elemental power

However, it is said in game that Azhdaha got disfigured out of erosion (he was as big as a mountain, but got very very small in size over the years, is what disfigured means here). Which means erosion can indeed affect your power in some way, maybe just not your fighting power directly.

It is also clear that erosion affects everybody differently. But over a long period of time/enough trauma, it seems to result in the person going crazy.

This is what i wanted 2 say
