New upgrade card idea: skeleton crew upgrade slot: none/ support crew effect: before you declare your attack, remove one die of you choice from the attack pool. Before moving, reduce the yaw value of any segment with a yaw value by one. Upgrade cost: -25 probably unbalanced but what do you think?

Eh I don't particularly like negative cost upgrades because it favors certain types of ships that don't need a buff. If it was non unique can you imagine what -25 pts per ship would do to ram spam.

May our CR90 B's block out the sun!

That or carriers who really truly don't need another buff.

Rather than broad stroke stuff like this, it is probably best to keep "fix it" upgrades solely to titles.

An OK idea

Make it less of a reduction (around -8 to -10 seems about right), uses the Officer slot and can't be used on flotillas.

Reduce yaw by 1 for each segment? Doesn't that reduce an awfully lot of ships to flying just straight ahead?

even spamming nav tokens you couldn't manage to swing around 180 in a game.

Make it something that takes a combat upgrade slot, to reinforce that it belongs on a combat ship. "Power Bleed Relay" (Turbolaser) - When you declare an attack against a ship, remove any one die from your attack pool. Still shouldn't be a very big cost reduction, because players are only going to use it in min/maxing scenarios.

I think it's a good idea, but it should work like Motti, based on ship size

Large base: -25 points
Medium base: -15 points
Small base: -5 points

If you want a negative cost, you need a few things to make it work.

First off, negative cost options should be a modification . This will prevent ships from just adding free dice and a few other tricks, but without necessarily preventing them from taking important or useful upgrades.

Second, it needs to reduce the ship's options without negating its core role.

I'd suggest:
Mass-Production Model: Modification, Medium and Large ships only - Title, -10 points: This title must be equipped to a ship with an Offensive or Defensive Retrofit slot. You may not equip Offensive or Defensive Retrofits.

Recon Patrol: Modification, Small ships only - Title, -5 points: when this title is equipped to a ship, it may not equip Ordnance, Ion Cannon, or Turbolaser Battery upgrades. This card cannot be equipped to flotillas.
