When to multiply?

In personal scale combat when using Destructive trait

Roll damage dice and apply Effect. Say 8. OK, I have that much.

Then apply the x10 to get to 80 damage and then apply armor (say 3) and protection (say 8 for a stone wall)? 69 in this case?

Or do subtract armor and protection first, get -3 in our example, and then have no effect even with Destructive?

In starship combat there are also Destructive trait and also the multipliers for bay and spinal weapons. Where do the multipliers happen there? The bullet point on p 168 of the Core Rules specifically states "AFTER TAKING INTO ACCOUNT ANY ARMOR..." emphasis mine. But if that principle applies it seems to be really reductive of stuff like final mounts. A spinal hit should pretty well eviscerate a free trader.

Querion Subsector 8-14 / 21 Planet & System Cards

This is the second group of seven planet and system cards for the Querion Subsector.

Prinx is a S-type Binary system so I have created two system maps Major and Minor.

Querion system has three seperate Planet cards. Erioque is a second planet with a higher than 1 million population. It is a major military base that no doubt will play an important role in the Fifth Frontier War.

Sheol is the first Gas Giant to get a planet card because it is the Homeworld of a species. Given that the terms used for theoretical lifeforms that live in a Gas Giant are Gasbag, Floater or Stinker I have chosen to use Jovoinoid as the discriptor.

Now for a bit of world building.

Retinae is the Homeworld for a pre-jump technological silicone-based lifeform that uses radiation for its biological processes. That presents a challenge - you need a planet that has existed for at least a couple of billion years to allow for evolution (the Ancients were only 300,000 years ago), but most heavy elements will have decayed long before that time to make a suitably radioactive environment.

Solution. About 800 million years ago an anomalous object - prehaps forged by a neutron star collision - collided with the former moon of Retinae, shattering both objects and leaving a dense ring of debris that has rained heavy elements down into the atmosphere allowing the evolution of a unique biology coupling silicone and radiation.

Why so many heavy elements remain in the ring and how it lead to a technological society is why Imperial Research Station Delta orbits the planet.

Also I am adding all new and updated planets and systems to my Dropbox as they are finished.

Link to Dropbox post Drop Box for all my Planet Information and System Maps

I plan to eventually finish the whole Spinward Marches but it will take quite some time.

As people always ask I created these using a software program called Universe Sandbox.

As always feedback and corrections are welcome.

Space combat with three "sides"

So I haven't run a space combat yet but I have an idea where it could happen and depending on how the PCs play their cards this could be a Mexican Standoff. Three separate ships, each hostile to the other.

Problem is, the abstracted nature of relative distance and vectors in the rules, while nicely streamlined, seem difficult to apply in this case.

For example, the range band between the PCs ship and both antagonist 1 and antagonist 2 are each separate variables, plus the range band between antagonist 1 and 2.

How do you track that?

How do you plot it out?

Is there an equation that helps constrain the differences between each of the variables?

I'm not a math guy!?

My head's gonna explode here!

AP on custom Gauss MFC vs CRB/CSC seems off...

So unless I'm missing something, and I'm pretty sure I'm not. It seems the design team goofed.

The Core/CSC Gauss pistol is 3d6 AP3 on that same token, the gauss rifle is 4d6 AP5.

But when building from the MFC, you get:
Gauss Pistol 3d6-1 AP3
Enhanced Gauss Rifle 5d6-2 AP5

Am I in fact missing a ruling or should I just use my best judgement? My work around if there is bad referencing on the part of design is to say pen +2 ignores the damage fall-off but +3 and up does as listed.

On the Clock - Negotiation with a Time Limit

Last year I was tinkering with a framework for handling long-term negotiations - letting players handle week/month/year-long negotiations in a way that didn't get bogged down in details, but which also had tactical decision-making, and which allowed the players be creative and play to their characters' strengths.

This did NOT make it into The Serpent. It's too formal and rigid - it made the players feel like they couldn't leave the main planet until the negotiations were done. But for a more structured campaign, e.g. where you DON'T want the PCs to leave the planet until the negotiations are done, it could work well.

So I've uploaded it here (Patreon link, but currently a public/free download; Traveller and Coriolis rules included), for any and all who can make use of or draw inspiration from this.

Reloading missiles

According to canon a standard (small) missile mass 50 kg and each launcher holds three per launch tube. How do you handle in battle reloads in your game if it ever comes up?

Older ship designs (by GDW and others) had gunners sitting in the turrets themselves so access was easy and the only problem was schlepping the 50 kg thingies from storage to turret. More recent design have turret control stations separate from the turret itself implying reloading externally which means a nasty space walk in the middle of battle.

So, how do you referees handle such reloads? Sure, turn lengths are long enough to facilitate reloads but who does the schlepping, what is the risk of being hit while on the outside hull during battle and so on, thoughts?

In Intercept the design system/software has a magazine option where you stipulate the capacity (great for those SDB designs for example) but doesn’t really handle reloads at all past that. Maybe having the Jury-rig team doing reloads?

Mercenaries & Equipment License Exceptions

Apologies if it's been answered, but can't seem to find it.

What proves a character is a mercenary, is it a roleplaying choice of the character in question or is there a more hard rule?

Best I've seen is having a military career at some point but I'd like to think there's a requirement more than 1-2 terms in a military career when trying to bypass Law Level restrictions. I know as GM I can just rule with whatever I like but I like to stick to RAW as much as possible.

What do travelers eat?

A while ago on Facebook I asked the traveller community what interstellar travellers eat. I still like the idea that they eat hard tack and related recipes, but what else do they eat?

Messiah

This is an adventure for Cepheus Engine.

Thomas Abe is a polished and professional looking man. He seeks passage to the religious world of Wuringeia. This world is located in the Sonora sector and is well known for producing it’s own version of the bible. This world is known to be very strict in regards to religious observance and customs.

Abe claims to be a religious scholar and has serious interest in the religious libraries on Wuringeia. He is willing to pay CR 100,000 for immediate passage to this world if he can be brought there within a fortnight. He has little in the way of baggage or cargo. This visit could easily be paired with some sort of trade mission. The Wuringeians often need mechanical parts, textiles, food and other such things brought to their planet. One could easily make a good profit on this deal.

Krafstoffschlepper - TL 10 fuel tanker

As I didn't include enough fuel in my previous deckplans, I thought I'd make up for that with this one!

Battery / Power Plant

RAW in Mongoose 2e explicitly state that "Only fusion and antimatter

power plants can generate the intense burst of energy

necessary to operate a jump drive". Is it within the rules to have a battery system in place that could meet the needs of basic systems in the amount of the jump drive's power requirement?

I don't want to design a power plant that can cover everything since it would be wildly inefficient.

thanks,
