When I read the 4e book cover to cover, I got the impression that at level 0 you got d4 hp + stamina modifier and then at level 1 you got your class die of hp but no stamina modifier (at level 2 you'd get it as usual).
My GM challenged this and on relook through I couldn't find what I thought I originally read. However, all the examples I found also do not specifically say you do/don't get it so I think I just put 2+2 together myself (maybe wrongly). It states clearly at level 0 you get stamina then at level 1 you get class die but doesn't specifically say you get stamina at level 1 that I see.
Does anyone have any example quotes one way or another? Note, I am looking for a specific quote answer (either from the book or creators of it). I can already see both ways so interpretations of wording I don't expect to help me. I also am aware of what the stamina section itself says. If providing the quotes I do know about here helps my answer please leave a comment, I can do it.
