### **Tier 1 (Siegecraft 1+)**

1. **Siege Weapon Mastery** – Mark a die as **Powerful** when using siege weapons; add the die’s face value to structural damage if successful.
    
2. **Emergency Repair** – Mark a die as **Risky** when repairing fortifications under fire; on success, restore structural integrity equal to the die’s value.

### **Tier 2 (Siegecraft 2+)**

1. **Breaching Charge (Siegecraft/Alchemy)** – Mark a die as **Effectful** when placing explosives; on success, collapse or breach a wall/gate section.

### **Tier 4 (Siegecraft 4+)**

1. **Grand Engineer** – Once per scene, you may designate an entire fortification (or siege weapon emplacement) as Reinforced; it gains +2 Soak dice and halves structural damage.
    
2. **Relentless Bombardier** – When you successfully strike with a siege weapon, you may immediately make another attack at –2 dice.
    
3. **Fortress Breaker (Siegecraft/Tactics)** – Any attack you lead against structures or fortifications automatically counts as a Critical Hit on margin of success 2+.

### **Why It Fits**

- **Fortification focus:** Control the pace of sieges, repair defenses, or break them down.
    
- **Synergy:** Crosses naturally with Tactics, Survival (sapper work), and Alchemy (breaching charges).
    
- **Cinematic escalation:** Tier 4 creates defining moments: demolishing walls or holding a bastion against impossible odds.
