Every Cover Object is built from a Material. The Material determines the object’s 💎 Hardness (Physical resistance) and ♨️ Energy Resistance (Energy resistance). 📏 Size, 🧱 Durability and 🧩 Cover Object Qualities are tracked on each individual object — a wooden crate and a wooden barricade share the same Hardness/Energy Resistance, but differ in Durability and which Qualities they carry.

This decouples what something is made of from how big and how reinforced it is. Adding a new Cover Object is as simple as picking a Material from this table and assigning a Size, a Durability, and a list of Qualities.

How to Use This Table

When stating up a new Cover Object:

  1. Pick a Material from the table — this sets the object’s Hardness and Energy Resistance.
  2. Assign a 📏 Size — this decides whether the object gives Half or Full Cover.
  3. Assign a 🧱 Durability value based on the object’s bulk and structural mass.
  4. List the object’s 🧩 Cover Object Qualities. The “Typical Qualities” column is a starting suggestion, not a requirement — a wooden crate is usually Flammable, but a wooden crate stored in a damp basement might not be.

Example minimal stat block:

Wooden Crate — Material: Wood (Hardness 3, Energy Resistance 2). Size Small. Durability 8. Qualities: 🔥 Flammable, Thin.

Notes on Specific Materials

  • Glass / Plywood / Drywall all carry Thin by default — these are cover you take in a pinch, not cover that holds up to sustained fire. Half Cover behind a window pane lets you ride out a single shot but rarely a second.
  • Upholstery is the lowest-protection material in the table on purpose. Foam and stuffing stop almost nothing — a sofa or a mattress is concealment, not protection. It earns its place by being bulky (full Concealment Bonus, no Thin) rather than by stopping anything.
  • Sheet Metal is intentionally close to Wood in Hardness — most car doors and appliances are surprisingly fragile to small arms. The Energy Resistance edge over Wood reflects metal’s slight advantage against lasers, but it doesn’t help against fire-based weapons (and the 🔥 Combustible quality on some appliances makes them actively worse).
  • Porcelain is dense but brittle. Its Hardness matches Sheet Metal and its Energy Resistance beats it — fired ceramic shrugs off lasers and heat — but porcelain fixtures carry low 🧱 Durability, so they shatter once anything gets through. A bathtub is the best cover in a bathroom; a sink is one shot from gone.
  • Lead trades Hardness for excellent Energy Resistance and unlocks meaningful ☢ Rad Shielded X values. A lead-plated wall is a defensive sweet spot against radiation explosives.
  • Reinforced Concrete and Vault Steel are intentionally high-end. Encountering Vault Steel as cover should feel like a major environmental beat — you’ve found yourself inside something pre-war.
