yes i somehow got him after 50 pulls as my first rare on his birthday

i got him at 56 pulls 2 days ago

Do you need really good luck or is it like 33%

More than likely it is only 33%. I've gotten AO as my first pull and I've seen others get Orochimaru or Sage as theirs.

same got Ao as first when i was totally sure i wouldn't pull Ao , i was saying for jinchu treasure when i saw 2 ppl on the server get Ao one after the other so i thought a 3rd Ao same day would be impossible so i pulled 40 as well ( did 10 prior and got a free draw in btw ) and guess what 3rd Ao pull on the server same day.
Atm the only people who have sage naruto on my server are the guys who brought him from events but one of the players quit after being top 1 for long because the server was dead and we never get sage world

i got him from my 3rd free draw on that tresure

Yeah I know that you can get sage naruto as first rare :D I got him as my first rare 2, only using 30 seals :P.
