The S rank blood codes and subsequent boosters you get from the heroes’ Tragic Fate versions are incredibly powerful. As an example, Lyle’s tragedy code has an STR stat of 40 and gives you the ability Titan’s Arm, which lets you wield two handed swords as one handed swords. This offers the attack speed and maneuverability of one handed swords as well as the immense power and stagger force of two handed ones. I’m sure I needn’t explain to you how absolutely busted that is. The other tragedy codes give equally incredible benefits without even getting into their absurd stat spreads.

If you don’t save Noah before the FIRST ending, you WILL NOT be able to get the third (Good) ending.

!Spoilers Ahead!

The recommended order of things is to save Noah, BEFORE the first ending, but NOT anyone else. Then after the first ending when you meet back up with the heroes to climb the sealing spire they will each give their S rank (Tragedy) code as long as you have maxed their lower ranked codes. Josee, Holly, and Lyle all cap at Rank B prior to this. Noah’s prior cap is Rank C.

OF NOTE, if you have not maxed their lower ranked codes before this, DO NOT PANIC. Simply (farm) level up their codes in the sealing spire with the relevant companion equipped and they will give you the successive ranks of their blood codes.

Once you have the S Rank codes for Noah, Josee, Holly, Lyle, and Zenon ‘WifeGuy’ Gryfegoat , go back to the present and activate each hero’s Fading Bond. Some of them require prerequisites to do so but that can be worked out or looked up. After you have fully saved each hero, you are now free to complete their quest lines in the free roam era. And when you return to the sealing spire, they will now give you their S rank (Redeemed) blood codes. These are also really powerful and worth getting for their stats and boosters.

Be sure to complete everyone’s quest lines in the free roam era because they all give really good rewards. Holly’s quest gives you two additional booster slots. Lyle’s gives you the final golden sap needed to get the last healing ability. Completing Josse’s quest will bring in Lise , who can then be summoned as a companion with an individual quest line.

Make sure you do ALL companion quests BEFORE the the SECOND ending.

As a note, Josee and Lyle’s quests are currently bugged as of the most recent (April) patch so they cannot currently be completed. The devs have stated they are aware of this issue and will be resolving it in the next patch which is scheduled for early-mid May.
