Suggestion for WOI Errata: Make Barrow's Edge work with unarmed piercing / slashing attacks, make ranged ikons work with ranged unarmed attacks

[power-pedigree]

This is something that can easily be homebrewed, but I noticed that RAW there is no way to use piercing unarmed attacks with any ikon outside of Hands of the Wildling, and no way to make ranged unarmed attacks with ikons. I feel like Barrow's Edge would give a fun 'vampiric' vibe to unarmed attacks that do piercing damage.

Just feels like a mistake that these werent covered since so many other options were covered. Thanks for reading my 2 cents
