I finally tried out the EstimAI mode with the "Dungeon of Echoing Lust" scenario with the Echidnus persona.
I'm not sure if I missed a setting, but after giving a "good" response, the intensity for the next pattern would shoot up to 75% or 100% of the maximum set.
It could also be that I skipped the chambers and went straight to the "boss."
The Eudaimonia mode at least ramps up the intensity is bearable increments.
Any suggestions for what I should try differently?
