Yeah...that character and example would need to be carefully examined because there are a bunch of red flags that simply pop out and scream "Potentially OP'd mayhem" to me. You , as Asp stated, need to list every single weapon, every single attribute and enhancement for said weapon and how it works with the character. Then you need to look at the preps you need to do those things, because you cannot simply just say it and it happens.
Remember if your weapon can do all those things and you change it, you have no preps behind that weapon so if you tried your run, shuriken thing, a 2+ prepped character can simple pound you or resist your move easily.
I will post my Templar move shortly in the Fey Wilds.
