Probability to get 5* Immortal Iron Fist?

Morpheus711

Kabam,
What’s the probability to pull a 5* Immortal Iron Fist from the max signature crystals?
Any plans on upping his prestige or abilities to actually get excited to pull him?
Thanks

Play the lotto first. More likely to win. Then you can buy tons and improve your odds.
