Insanely high cost of starship components. Is craftsmanship part of component aquisition rolls?

By DrSnake, in Rogue Trader Rules Questions

Do you factor in quality of starship components when making an acquisition test? It seems to send component costs through the roof.

Pg 274 of the core rulebook says that you do, but on 207, it states that the acquisition threshold should only be "determined by availibility (and perhaps craftsmanship)

Battlefleet koronus has updated rules for best quality components. When making an acquisition test for a best quality component do we only count the increased craftsmanship SP cost increase as part of a higher rarity when calculating the acquisition cost? Or do we take into account both higher rarity and higher craftsmanship?

I ask because ship component costs seem to skyrocket out of proportion when taking everything into account.

Here is the breakdown of a best quality mars macrocannon, not taking craftsmanship into account (only higher rarity from the derived SP cost:

-30 from war component scale cost, -20 from 3 SP (very rare). -50 to Acquisition tests. Difficult, but reasonable. Same cost as an Atomic.

Taking the best quality craftsmaship modifier into account (-30). It becomes -80 to acquire. For reference scale a -80 modifier is equivalent acquiring 10,000+ suits of best quality power Armor.

(Think for a second how absurd that is, then come up with a plan to conquer the calixis sector)

If you are trying to acquire a best quality Godsbane Lance, you are looking at a -110 modifier if craftsmanship is taken into account. You might have to burn 12 or so profit factor to even have a 50% chance of getting one.

An avenger class Grand Cruiser would only be a comparatively modest -90, for reference.

The values do not seem so out of the norm. I think the price represents the difficulty of getting good quality components and in addition the concentration of resources into a single ship. They look fine to me.

Best quality components are simply, by RAW, out of range for most RT's. Go take one from someone else.

The +1/+2 to ship point cost is only for beginning the game / making a ship with good / best.

After creation you use the -10 / -30, and price them (ship points wise) without the +1/+2.

Remember that buying them at an Imperial Navy shipyard makes the test a bit easier.

Trying to buy them at a dedicated Forge World (possibly through a player with Peer or Good Reputation [Adeptus Mechanicus]) should give an even bigger bonus.

I have no idea at all why FFG left out the guidelines for using Forge World shipyards, most groups seem perfectly willing to make huge detours just to visit the Lathe shipyards.

How did you arrive at that? The text seems to indicate the opposite.

"When calculating the Component Costs and Availability always use the modified Ship Point costs (taking Component Craftsmanship Modifiers into account)." BFK p. 18

I think I figured it out here.

BFK Table 1-6 + RTC Table 9-36 are the charts you need at this point.

BFK Table 1-6 covers both availability and craftmanship

RTC Table 9-36 deals with component type in terms of scale

So yeah the rules make sense and if you use class bonuses and situational bonuses it makes it easier to get them.
