You sort of can but its very long winded. The big creatures that throw curses at you in Hidden Valley drop them but they stop spawning after so long so you'd either need to use bonfire aesthetics or do it over the course of several ng's (ng, ng+, ng++ and so on. You'll need 3 playthroughs anyway to get the plat)
