Eternal Bonds: Completion

Eternal Bond with Jinai is completed and Jinai is summoned.

Once 29 days have gone by, on the 30th day, you will receive your hero. The reward can be collected via mail from Yorm and once you select [receive], the Fated hero is automatically summoned in the traditional way. You can find Jinai in [manage heroes].

Here's a tiny but comprehensive guide as to why she's so useful.

Eternal Bonds

This is a new feature that can be accessed as you progress through the story. You will typically choose between two heroes and start what is known as an Eternal Bond.

Conditions for Eternal Bond:

Log in consecutively for 30 days and you will receive a Fated Hero or their corresponding Fatecore.

Each day, you will be granted a reward as ‘motivation’ to continue the bond. You can expect to receive 30 rewards for the 30 days.

You can only start a new bond if you complete or destroy the old one. If you destroy the old bond, you must wait for the Hero to show up again.

A bond can be recovered if ‘disrupted’ (a few days where you didn’t log in) for a cost.


Personally, I think this is an awesome feature (especially for f2p) and a great motivator to log into the game. It doesn’t cost any currency and you are guaranteed to get the Hero of choice.

The second season of Eternal Bond is between Shufraken or Dorka which showed up while I was bonding with Trickster Jinai. Since I’m already on day 12, there’s no way I’ll break the bond but both are great units.

Update: I had plenty of time to finish my bond and start a new one with Dorka.
