How many shards to get someone to 5 stars?

0 -> 10 -> 25 -> 50 -> 80 -> 145 -> 230 -> 330
The respective differences are the amounts needed to gain 1 star.

Nice. So, 29 days starting tomorrow, maybe a couple days less if I can eke out my Arena rank up to get a extra 100 marks every so often, I can get Eeth Koth and have him at 5 stars. By that point, my Mace Windu will be five stars, QGJ, and maybe for kicks Ahsoka or Jedi Guardian, and then next Yoda event, I can finally get him.

I rank first in arena, finish almost every single GW even when it seemed impossible. I even spent Catina credits to level up ashoka to 4 stars. I have 5 Jedi unlocked and though I'd really like Yoda, there is no way in hell I am going to stop using all my shards for Daka over that pice of shit.
