Vehicle System Damage and Critical Hits

Critical hit table for vehicle combat.

When a vehicle takes a critical hit, roll 1d8 on this table (or 1d12 for exploding effects on a natural 20). The effect applies IN ADDITION to the round's normal hull loss and applies immediately. Multiple criticals can stack: each adds its penalty until repaired.

Repairing a critical requires the Repair skill (or Engineering for engine hits), DC 12-20 per entry, taking 1 hour per critical. Repairs during a chase require Drive/Vehicle DC 15 to perform without losing a Drive action that round; the GM may allow the Repair attempt as a Pass action.

This table is the vehicle-scale analogue to the void warfare system damage table. Where void warfare criticals cripple ship systems, vehicle criticals cripple chassis systems. The 1d8 (or 1d12 for natural 20) die is smaller because vehicles have fewer discrete systems than ships.

Crew effects from criticals apply to the relevant crew Station: an Engine hit Driver-Pilot Fort save, a Crew Hit roll a damage Reflex save, etc. See spec-vehicle-combat S6.3.

Exploding Effects / 9 / System	Engine (Exploding)
Roll Die	1d8
Roll Die Sides	8
Thresholds / Threshold 50Pct	Vehicle reaches 50% Hull → -1 Handling, 50% jam chance per round on a random hardpoint (Repair to unjam).

Notes

Exploding Effects / 10 / Effect: Vehicle catches fire; damage same as Fuel Line + 1 ongoing 1d6 fire damage per round to crew; explode on round 5 unless extinguished.

Exploding Effects / Note: On a natural-20 attacker roll, expand 1d8 to 1d12 and apply the listed additional complication. Cumulative criticals at the same system double the effect and +5 DC to repair.

Thresholds / Threshold 10Pct: Vehicle reaches 10% Hull OR takes 3+ criticals in same round → Wrecked unless towed; 5% per round chance to explode from fuel/ammo fires.

Thresholds / Threshold 25Pct: Vehicle reaches 25% Hull → -2 Handling, Drive declarations limited to Cruising or Hold; system damage fires spread to one adjacent system each round.
