I ask this question as I am trying to empty the Pact of Fellowship pool, and am thinking of doing the same for Pact of Fate (because I want those Luck chests).
I understand that recoding a character allows you to inherit 100% of that character's luck, plus 20% from each of the monsters used to recode.
I also understand that recoding a character that you already have the Λ form of will add 5 Luck.
My question is: Is the additional luck just straight up 5, or do you also get a bonus from the luck of the just-recoded character?
Ex. Assume I have a Suoh Λ with 10 Luck. If I recode another Suoh with 50 Luck and monsters with 50 Luck each (so 50 + (50 * 0.2) + (50 * 0.2) = 70), will my Suoh Λ have 15 Luck (10 + 5[Existing Λ Recode bonus]) or 85 Luck (10 + 70[new Suoh Λ] + 5[Existing Λ Recode bonus])?
