Not completely true. When I said that, I was specifically thinking of undergrowth, which is a physical object (well, a bunch of physical objects) that grants concealment. I could see a rogue diving into the undergrowth for Evasion. Similar situations could apply with other physical objects that grant concealment.
Then that brings up a second question: Does it take the same amount of time to refill my supply of one ingredient (which would take one shop) as it does to fill up my supply of ten different ingredients (which would take a bunch of shops)?From my perspective, the answer is YES. The bulk of the time is not spent collecting more of a single component, but shifting from different shop to different shop.
Cool. That helps.Also, I've halved all refill times for convenience if you check the rule.
Yes. Very much yes. Though I actually like hit points, even from a realism perspective - but that's a completely different tangent.
