But I should mention that it looks like I'm getting the discount of level 5 master alchemist when I only have 4 of the levels so far. The price of potions for me seems to be SL*CL*20 that is.
I suppose it's arguable whether it's a feature or a bug, but I also noticed being able to brew potions at CL1 that I wouldn't expect to. For example waterbreathing at CL1 which is... nice, one hour, low cost... but then there are elixirs of Mislead and Superior Resistance that I can also brew at CL1. I expect that was not intended ^^
A small thing but I also found I could scribe scrolls of Gromph's Combat Readiness at CL3 for a price of 150 + 60 when I expected 2 * 3 * 15 = 90. That's not something that's going to keep me awake at night but it's curious
