Alrighty,
So having the character you use to loot all the things have high luck is actually really neat! Especially in act 2 with all the millions of smelly fish piles.
Have you guys been using it and what are your experiences?
I'm asking because I have to restart and thinking about making a looter character.
Update
I've now completed Act 1 on my new playthrough with a dedicated looter with now 7 Lucky Charm (4+3 gear) and I'm drowning in gear.
To reiterate, LC can proc on every chest, box, pile of bones, fish, bucket, barrel or heap of flesh out there. You start finding epic at 4 LC, and it happens quite frequently. I have no clue if I can find legendaries as well. We will see

Update II
Found a legendary in the 3rd fish pile I looked at in act 2
Still at 4+3 LC
Update III
4 epics and 1 additional legendary before even getting to Driftwood.
I'll stop updating this now, I think anyone stumbling upon this post can get the point

Good luck adventurers!
