[@Kenshi] sorry, doing the loot rolls early means I don't have everything properly formatted yet. The jist is:

Tier 1 to be useful for PCs, but have minor effect on NPCs.
Tier 2 tend to give PCs a strong advantage or push NPCs into a tough spot.
Tier 3 tend to drastically alter the entire dynamic of the story and NPCs must deal with the fallout.

I'm playing some Valheim this evening but hopefully might have some time a bit later today to give more info. If not I can expand upon it more tommorrow.

[@Lucius Cypher] hmm, I'd need some time to think about that one. Typically edges don't make you better at killing things though it is possible to grant +position or +effect. Either way, that'd be a tier 2 item since it affects NPC so you can't draw it as your loot this time around.
