Yep, 5e very authentically evokes the classic game by having 1st level PCs that can drop dead more or less instantly. Warms my grognard heart, it does.Any suggestion are appreciated.
Back in the day, we'd give 1st level PCs max hps (5e already does) and add a d6 on top of that on the theory they were your '0 level' hps. Another trick back then was the 'brevet' - a character starting at 2nd, or even with just 2nd level hps, but 0 exp.
An extra HD at 1st has also been suggested and wouldn't hurt.
In 5e, just starting above 1st (3rd is a good option) is perfectly reasonable.
