Not to defend the Nazis here, but working prisoners to death predates them by a couple millenia. They just did it on an unprecedented scale.

Ironically, what the Nazis did in the extermination camps was mass executions, i.e. the very thing anon finds wasteful.

In German, those professions actually have different names. The furniture maker is a Schreiner or Tischler (lit. “tablerer”), while the builder is called Zimmermann (lit. “room man”).

The German bible correctly identifies Jesus as a Zimmermann.

That’s why you buy a box of 36 small d6.

And then 5e came along and changed half the spells to use d8s instead.

At 14 con (which is a reasonable to high con for a caster), there’s a 35% chance to fail this check. Even with advantage (e.g. war caster), there’s about a 12% chance.

If your DM consistently sends casters with higher con saves, he just really doesn’t want you to ever break it.

And that’s coming from someone that has a cloud giant wizard with a +10 con saves as the BBEG last session.
