For sure in the betrayers book Hidetsugu bit Hisokas head off and Takeno took one for the team from a stone flung free from the O-Kagachi after that i will have to think......
been looking at the threads, if in fact " Epic " is a keyword or mechanic in anyway i was thinking along the lines of maybe epic battle scenes? so the other speculations on the epic sorceries and instants might be going somewhere... just a thought
but then again anything is possible i guess
