C3 raiden damage increase

Hey peeps I’m new to this sub so I’m not sure if I’m really supposed to ask this question here but what sort of dmg increase are you looking at if you pull for c3. I’m at c2 atm and I love raiden but I’m wondering if it’s really worth it. I also really want to pull for mauvika and arle so I’m really torn (I have 150 wishes saved and didn’t win 50/50 last time if that makes a difference)
