Cardboard Hat

The Cardboard Hat is a common head armor found in The Alley, part of the Cardboard set. It gives +2 Shield but comes with three significant downsides: Fragile (reduced durability), Flammable (vulnerability to fire damage), and Brittle when wet (takes extra damage if the Wet status is applied). That's a lot of conditional weaknesses for a modest Shield value.

The Cardboard set includes six other items and has its own set bonuses, which is the main reason to wear this despite the liabilities. If you're not building around the set, the +2 Shield rarely justifies the exposure. In encounters with fire or water hazards it becomes a real liability.
