Handmade is the lowest tier of Rarity available in Save the World. Weapons and Traps of this rarity are only available as rewards for early Stonewood Quests. They cost less resources to craft than Common items, but in exchange have worse stats, do not have Perks, and cannot be Upgraded or Recycled and therefore are not very useful unless you have no other options.
List of Handmade Items
The rarity "Trainee" is the equivalent of "Handmade" for People cards. Currently the only Trainee-rarity card is the Rifleman Trainee Defender. Similar to Handmade items, Trainee cards cannot be Upgraded or Retired.
