Who should I give the Magic Healing Beer to?
Saving Edmund nets you Brewery equipment upgrades worth +100% Yield, +75% Brewing Speed and +40% Quality. (H/T Spartacus - any chance you could clarify if those upgrades stack with or replace the brewery gear you may've already purchased?)
Saving Gary, by contrast, unlocks him as a new employee for the Brewery. He works for free, has Dex and Craft scores of 10, and Int and Patience of 6 and 4 respectively. He also adds +50% Quality of all batches brewed.
