It has everything you need (except lessons):
- A horse (only in the class selection menu, and still no lessons)
- A UI element
- A kill icon
- A name
It also causes all Heavy Knights to march in time with each other when using the lance (it never occurred to me to meddle with the sword & shield animations until this exact moment, and I'm not meddling with it again after I've gotten it all working just right).
Will not increase your range, probably because you never took any lessons.
