# Morrigi FTL Travel

The Morrigi use a gravity based drive to their main method of FTL propulsion. Unlike other races, the Morrigi FTL speed does not increase as the power plant moves from Fission to Fusion to Antimatter. The only difference that a more advanced power plant has on FTL movement is that it increases the range of the ships. To increase the FTL speed of an individual ship, the Morrigi need to research the two upgrades to their Void Cutter Drive system: the Void Carver Drive and the Void Mastery Drive. But there is another way to increase the speed Morrigi ships.

## Flock Effect

As more ships are added to a fleet, the speed of that fleet also increases. But there is an upper limit to this "Flock Effect". Normally up to 10 of each class can influence the speed (20 with Grav Synergy). Larger ships add more speed, and Gravboats add a fixed bonus dependent on their class.

A gravboat with a lower base speed than the rest of the fleet can sometimes slow the fleet down, depending on specific circumstances.

The following formula can be used to describe the expected speed of any fleet:

``` Fleet Speed = ([1+(DEs * .05)+(CRs * .1)+(DNs * .15)] * base speed) + gravboat bonus
Only 10 ships each class count normally, Grav Synergy boosts to 20 each class.
The Gravboat bonus is: DE size = 1, CR size = 2, DN size = 3
```

## Fleet Speed Examples

Here are some examples of the above formula in use:

A full DE fleet, Void Cutter Drive, no gravboat:
- 10xDE = ((1+.5) * 2) = 3

A full DE fleet, Void Cutter Drive, DE gravboat:
- 10xDE + DE gravboat = ((1+.5) * 2) + 1 = 4

A Mixed DE and CR fleet, Void Cutter Drive, DE gravboat:
- 7xDE + 3xCR + DE gravboat = ((1+.35+.3) * 2) + 1 = 4.3

A full DE and CR fleet, Void Carver Drives, CR gravboat:
- 10xCR + 10xDE + CR Gravboat = ((1+.5+1) * 3) + 2 = 9.5

A full DE and CR fleet with one DN, Void Carver Drives, CR gravboat:
- 1xDN + 10xCR + 10xDE + CR Gravboat = ((1+.5+1+.15) * 3) + 2 = 9.95

A full DE and CR fleet with one DN, Void Carver Drives, DN gravboat:
- 1xDN + 10xCR + 10xDE + DN Gravboat = ((1+.5+1+.15) * 3) + 3 = 10.95

A full DE and CR fleet with one DN, Void Carver Drives, DN gravboat, Grav Synergy:
- 1xDN + 20xCR + 20xDE + DN Gravboat = ((1+1+2+.15) * 3) + 3 = 15.45

A full DE, CR and DN fleet, Void Carver Drives, DN gravboat:
- 10xDN + 10xCR + 10xDE + DN Gravboat = ((1+.5+1+1.5) * 3) + 3 = 15

A full DE, CR and DN fleet, Void Mastery Drives, DN gravboat:
- 10xDN + 10xCR + 10xDE + DN Gravboat = ((1+.5+1+1.5) * 4) + 3 = 19

A full DE, CR and DN fleet, Void Mastery Drives, DN gravboat, Grav Synergy:
- 20xDN + 20xCR + 20xDE + DN Gravboat = ((1+1+2+3) * 4) + 3 = 31
