Lets see...I remember dying---

2 times on first seymour
1 at the Chocobo eater :shame:
1 at Defender x
1 at Spectral Keeper
1 at Yunalesca
I died a few times fighting BFA because yuna was low lvl.
and I do remember dying once from a bohemoth king (the thing that does meteor after you kill it).

So add the couple stupid deaths I usually get and we get...

12 DEATHS...This was the first time I played though, Ive played though a couple more times without this many.
