I think its Change Bad Event Probability or something like that. Its in the abilitys somewheres. That would be kinda cool to have warp drive and impulse drives for a star trek mod or something like that
I think it would be best to make cheaper wormhole opening things, then make a component that affects the probabilty of bad events in a sector only. You could also make base components that make it so that bad events CAN'T happen in a sector as well... So you could have Warp Pathways(make one with Decreace Bad Event Probabiliy 100 and Open and Close wormhole) and then make Wormhole Highways...
