What changes
Soy Milk still lowers hidden calculated damage. Later upgrades may need to catch up before the displayed damage rises.
How to approach the setup
Take Rock Bottom before Soy Milk. Taking it afterward does not restore an earlier damage value.

The caution to remember
The protection depends on holding Rock Bottom. This guide does not calculate a full item stack.
What this teaches about a run
A preserved HUD value can hide changes underneath it.
