3. Ethel Joins Your Party

Ethel will join your party after completing the Hero Quest, No Want of Courage. Noah will be able to switch to Ethel's class, Flash Fencer, right away, while the others will need to finish a certain number of battles first with Ethel or any Flash Fencer before it unlocks on them.

Take note that Ethel will leave the party after announcing your departure from Colony 5 so be sure to unlock her class on your party members before progressing.

7. Valdi Joins Your Party

Completing the Hero Quest, The Kind Right Hand, unlocks Valdi as a Hero for your party. Lanz will be the initial inheritor of his class, War Medic. This class specializes in healing, making it an excellent addition to your party if you still lack survivability.

18. Execute an Ouroboros Order

Starting from the second boss battle, you will now be able to execute Ouroboros Order during Chain Attacks. Ouroboros Orders only appear in the order selection after successfully executing orders from an Ouroboros pair.

For example, you will need to execute orders from both Noah and Mio before their Ouroboros Order, Death of 1,000 Cuts, becomes available on the selection.

Ourboros Orders deal massive amounts of damage to your target, but will instantly end the Chain Attack unless you initiate the Chain Attack with an active Interlink at Interlink lv3.
