wonder if Ubisoft would allow the heavy shields to be used like light shields where you can walk around whilst using shield defending strikes instead of just standing in one place defending

I already mention the secret isu bow, but there seem to be more such items still hidden for us to find.
i for one would like to know what else is out there.

This guy has gathered some more clues, or rather he combined all current clues in a video:

So guess what...once you have farmed many runes even though you can hold them all in your inventory the game limits you in what you can access.
This is, i cant find certain runes now that i am trying out a new build, yet when i go to my inventory they are clearly there.
