The last supplies I need to build the Blacksmith's Forge are damaged manikins and peerless rapiers. Where can these be found? I'd like to focus my efforts in the lost grove on fighting the specific enemies that drop those or whatever.

Rapiers drop from the Captain elites and their boss, Elaine. You can also get them rarely from chests

the manikins can drop from all elites and bosses (and again, rarely from chests)

Thank you!!
