Hello, JAX 2 Scrolls!
First of all, I didn't have any intention to call you a liar. Sorry if you had such feeling.
Let's start all over:
1. If we talk about how Geists can be used for Champions:
- increase Champion's Rank.
- increase Champion's XP.
Increase Champion's Rank.
You need to take into account two things here: Rank and Grade.
You will be able to use Geist to increase Champion's Rank only if this Geist has the same Rank and Grade as Geist does.
Increase Champion's XP.
You're right. The number of XP you get depends on the Geists' Rank, not Grade and Rank not Grade should be said here: https://www.screencast.com/t/2fOhXh8W
I'm sorry for not understanding you at once. I've already created a task for our localization team on updating this information.
