Hello all, I had this situation come up in a game recently & decided to create a maneuver out of it.
PC's ship was following target ship @ warp and wanted to bring them out of warp. I ruled that the could fire a spread of torpedoes and have them detonate just in front of the target ship in order to collapse the warp field.
Here is my suggestion for the maneuver, all input is welcome
Collapse Warp Field
Type: Tactical
Tier: 2
Pre-Req's: Target ship & your ship travelling at Warp Speed, Match Speed, Range = Point Blank, Torpedo Launchers
TN: Ships Protection+10
Durration: Warp Field Collapses for as many rounds as indicated
Marginal Success, 1 Round
Complete Success, 2 Rounds
Superior Success 3 Rounds
Extraodinary Success 4 Rounds
effects are halfed (to a min of 1 Round) if the target ships Engineer makes a Propulsion Engineering (Warp Drive) roll of TN25
If the test is failed, Firing ship takes 1/2 of the penetration value of the torpedo in splash Damage & Conn must make a System operations(Flight Control) TN 15 test to avoid collapsing thier own warp field. Due to their nature, Plasma Torpedoes can not be used.
Thanks
