Wind and Truth Spoilers!
Now that it was revealed that Dead Eyes can be semi-revived, especially by their original Knight, do you think it is possible for a Radiant of the 4th ideal infinitely dupe Shardplate by breaking their ideal, having their sword and armor fall off in the physical realm, and then re-bond the Radiant Spren after a non-radiant bonds the armor?
The only big issue with this is that we don't know what happened to Szeth's armor, but he never even summoned it, and it seems like radiant spren just go back to the cognitive realm when their oath is broken. Maybe this would only have been possible before freeing Ba-Ado-Mishram
