| Pip Increase | Difficulty | Cost | Mishap Modifier |
|---|---|---|---|
| +1 | Moderate | +10% | +1 |
| +2 | Difficult | +15% | +1 |
| +3 | Very Difficult | +25% | +2 |
| +4* | Heroic | +35% | +3 |
*Due to current technology standards, it is impossible to improve the Space by more than four.
Characters roll for mishaps whenever complications happen when they roll for pure speed (e.g., a race against other ships) or when going above the drive's original speed.
Minor Mishaps
| Roll | Result |
|---|---|
| 1 | Engine power transfer conduit blows out. Space is -2 until repaired(Easy repair roll). |
| 2 | Drive system stalls. Ship must continue at same speed for 2 rounds. |
| 3 | Power surges increase difficulty of all maneuvers by +5 for 1 round. |
| 4 | Engine reaching unsafe operating parameters: ship must make no maneuvers for next 2 rounds or circuits burn out, adding +10 to the difficulty of all maneuvers until repaired(Easy difficulty). |
| 5 | Engine power surges. Add +5 to the difficulty of all maneuvers, including landing. Repairs cost 10% of engine cost. |
| 6 | Engine power conduits blow off. All maneuvers at +10 to difficulty until rerouted(Moderate repair roll, takes 2 rounds). |
Moderate Mishaps
| Roll | Result |
|---|---|
| 1 | Power surges. Add +10 to the difficulty of all maneuvers for 2D rounds. |
| 2 | Drive circuit link failure. Roll 1D at the beginning of each round. On 1-2, controls are considered ionized for that round. |
| 3 | Engine power transfer conduit blows out. Space is -2 until repaired(Moderate repair roll) |
| 4 | Drive system stalls. Ship must continue at same speed for 2 rounds, maneuverability considered 0D for five rounds. |
| 5 | Temporary drive failure. Ship is dead in space for 1D rounds. |
| 6 | Engine reaching unsafe operating parameters: ship must make no maneuvers for next 2 rounds or circuits burn out, adding +10 to the difficulty of all maneuvers until repaired(Moderate difficulty). |
Catastrophic Mishaps
| Roll | Result |
|---|---|
| 1 | Engine overloads while landing or docking as a result of stresses. Replacement parts cost 25% of the original cost of the engine. |
| 2 | Engine overload. Engine shuts down, with no thrust, maneuverability is effectively 0D. Add +15 to all astrogation difficulties. |
| 3 | Engine overloads and is destroyed. Must be completely replaced. |
| 4 | Engine overload. Engine destroyed, must be replaced, anyone near the engine compartment suffers 4D damage from the explosion and smoke inhalation. |
| 5 | Engine overload and power surge. Engine destroyed and disables hyperdrive(Difficult repair roll to fix). |
| 6 | Drive system fails as ship is on final approach for landing. Pilot must make Difficult piloting rolls not to crash the ship(5D damage to all aboard if ship crashes). |
