Yes, this. It's the lazy way, but I found it more enjoyable to farm there alongside other IRL tasks than I did running around the woods in other scenes, and spending more time fighting elves or wolves instead of reapers. The reaper there always spawns in the same spot, and there's nothing else around, except a brown bear that can get annoying sometimes if you're too close to it while waiting for the reaper to spawn. The reaper has a respawn timer of five minutes. Kill it, do something around the house, kill it again, etc.
