Hoe Radius and Reset Terrain; Reset terrain allows you to reset any modified terrain to default. Hoe Radius allows you to decrease or increase the area the hoe attempts to modify. Also influences the reset radius.

Mass Farming or Farm Grid; Mass allows you to plant by default 5x5 plants in an evenly spaced grid, still consumes stamina for each of the 25 plants as well as durability. If you're short stamina you'll only plant what you have enough stamina for. Farm Grid gives you snap points on plants.

Timed Torches Stay Lit or Torches Eternal: Stay lit allows you to have torches that turn off during light and on during dark without consuming fuels. Eternal disables fuel consumption as well.

If you really like to build stuff; BuildShare BepInEx Version is nice. It allows you to convert buildings to files so you can share them or build them exactly how it was saved in a new location. This mod may require watching a tutorial to fully understand how it works.

If any of these mods break, you can simply remove the plugin and play normally as they are minor augments.

Valheim Plus is prone to being broken upon most of the updates that Valheim receives, which can mean you get stuck waiting for updates or risk some problems with your world if you've chosen to increase the build height or other major changes.
