I am coming back after a long break, so can someone point me to the right thread or elaborate on this a bit?

I have:

1 fortune fob-20% reroll
2 lucky relic-10% luck
3 hisha-10% luck
4 cupcake-7% reroll
4 9% luck in eq that I am wearing.

Is my total 56%? Now, with luck elixir 30% is it 86%?
Or is it 39% luck and 27% reroll, with luck elixir 69% luck and 27 reroll?
Thanks
