Ranger MF Culler

I'm new to PoE and I have a Friend who says a MF Culler build is pretty great and they need one in their group I'm also an ex Diablo 3 Player, However I've been searching around I didn't find any good Ranger MF Culler Build can someone please help me out here?

I think barrage + chain might be pretty good.

I had a friend use lightning arrow; but that was a long long long long time ago.

Split arrow might be the best if you need to save some gem slots.

I would strongly caution you against playing a magic finder for one of your first builds. They deal no damage, you can't solo effectively, and personally I find them quite boring.

If you are sure you want to play a magic finder, it's not all that difficult to build. As a ranger you can just pick a bow skill (personally I would recommend tornado shot), then look up a guide for the skill. Since there is no magic find in the skill tree, you can build your build the same way other people do. I would highly recommend looking for an elemental version of your chosen skill since physical gear can be really expensive. The main difference between a magic finder and a regular build is gear. You always want to be running the increased item rarity gem in your skill as well as culling strike. Most magic find builds use two separate links with the same skill. For instance, you might have one tornado shot linked to lesser multiple projectiles, weapon elemental damage, and faster attacks which you use to deal damage, then another one linked to culling strike, increased item rarity, and greater multiple projectiles for when you are getting a boss' health low. You want to get as much increased item rarity and increased item quantity as possible on your gear, but capping your elemental resistances at 75% is much more important.
