Conversion problem that has me wondering...

Okay the radiation systems are totally different. GW is 3-18 against CON on a chart that tells you then how bad, bad is per the PCs ability to withstand the radiation. In SF the Gamma Dawn rules are the S/R (!) type. 

Now S (intensity, strength, severity) can be glossed to GW as best as I can figure as follows:

In GW level 18 radiation even if you have an 18 CON is a D on the chart, D means 20% mutation 80% Death, not a happy place to be for one's PC. According to Gamma Dawn the only way PCs would get a 1 time exposure with auto 20% mutation is if the S rating was 100, because you get your % chance to mutate by dividing 5 into the S#. Oddly in Gamma Dawn S is treated as an ability handicapper versus STA damage, where as in GW it nails your Hit Points.It seems like it should do both to me, as radiation exposure is no fun for the body. So here is what I am thinking for S. It isn't perfect as 1 + 2 levels do nothing in GW but S5-10 could mess with a PC in SF.

GW# ='s a range in S

1 = 1-5

2 = 6-10

3 = 11-15

4 = 16-20

5 = 21-25

6 = 26-30

7 = 31-35

8 = 36-40

9 = 41-45

10 = 46-50

11 = 51-55

12 = 56-60

13 = 61-65

14 = 66-70

15 = 71-75

16 = 76-80

17 = 81-89

18 = 90-100+ 

Unfortunately I have no idea how to treat R other than my best guess, a quickly disappearing radiation in GW I am figuring is a R1 in SF.  I figure the R could last in SF 1-100 days but 100 seems pretty high since Radiation Sickness rarely goes past 8 weeks as I understand it... so rounding up to SF weeks 60 days but it seems you usually die if you are sick for 8 weeks or more from what I can tell, I am not an expert on this stuff. But R1-R60 seems reasonable... input on this welcome.

Now in Gamma Dawn the S affects the ability rolls, in GW the intensity affects hit points. So the question is should Radiation exposure result in STA damage not just abilities?

I wrote an article on radiation with a mechanic that similar to the one used for poison, diseases, and infections. For fun and fluff I included symptoms based on frontier species. Can't remember which FE that was though. Edit: SFman 17

I will look for it...

SF's general system allows for a greater variety in the Radiation, where as GW's & MA's systems are a chart and with variablity based on the PC's stats. So a bit harder to gloss than most things.

I am thinking on some critters we will have to discuss how best to fit the rad, toxin ect effect in SF on a case by case basis. 

I am wondering since Rad durration in SF is listed per day = 20 hour exposer maybe for exposurer that does things different I should consider expanding how to notate it...

So if I want 80% death or 20% mutation for each melee of exposure it might look like this: 

S100/(R1!)

(M=20% D=80% per turn)

So every Turn the PC is exposed they must roll for mutation or death if % chance of not rolling death% by the end of a 20 hour period would be pretty low I think so anyone dumb enough or incapacitated to stay in deadly radiation would die by the end of the day.

Maybe I could denote damage to STA some way to that is logical too.

I found the Article, SFMan #17:

So if 30 is top exposure stat instead of 100 maybe this: 

1 & 2 in GW cause no damage to PC's and are generally not used however to convert back and forth I need those low level exposures. So how about this?

1 -5/R10 D=no M=+1% per day not treated (+1 minimum to +10% maximum)

2 -5/R20 D=no M= +1% per day not treated (+1% min to +20% max)
 
3 -5/R30 STA M= +1% per day not treated (+1% min to +30% max)

4 -10/R10 D=no M=+2% per day not treated (+2% min to +10% max)

5 -10/R20 D=no M=+2% per day not treated (+2% min to +20% max)

6 -10/R30 STA M=+2% per day not treated (+2% min to +30% max)

7 -15/R10 D=no M=+3% per day not treated (+3% min to +10% max)

8 -15/R20 D=no M=+3% per day not treated (+3% min to +20% max)

9 -15/R30 STA M=+3% per day not treated (+3% min to +30% max) 

10 -20/R10 D=no M=+4% per day not treated (+4% min to +40% max)

11 = -20/R20 STA M=+4% per day not treated (+4% min to +80% max)

12 = -20/R30! D=yes M=+4% per day not treated (+4% min to 99% max) 

13 = -25/R10 D=no M=+5% per day not treated (+5% min to 50% max)

14 = -25/R20 STA M=+5% per day not treated (+5% min to 99% max)

15 = -25/R30! D=yes M=+5% per day not treated (+5% min to 99% max)

16 = -30/R10 STA M=+6% per day not treated (+6% min to 60% max)

17 = -30/R20! D=yes M=+6% per day not treated (+6% min to 99% max)

18 = -30/R30! D=yes M=+6% per day not treated (+6% min to 99% max)

I know the -5/-15/-25 is not in the article but I used the same pattern and works with GD rules for Mutation chance and allows me to match the GW #'s better. I topped off mutation chance at 99% because there should be a 1% chance nothing happens in my opinion.

So what do you guys think?

Well 30 was perhaps arbitrary but some of the data I found on RW radiation posioning said things like at level X 50% will die in thirty days so I use 30 days as a number to play with. The goal was to create a mechanic that was AD compatible, matching existing mechanics for poisons and infections. The problem was that sources of radiation could be severe to mild and the length of exposure was also variable and I tried to account for those things without bogging down the rule mechanic too much. There is actually no reason you couldn't develop a whole new mechanic for what is clearly Gamma Dawn type setting. I simply did some ground work for including radiation poisoning in SF.

The fastest way to incorporate radiation exposure in setting would be to inform the PCs that the yatch or priveteer they were on during the KHs battle lacked military grade radiation shielding and since the vessel was struck by several beams that are ionizing radiation they have hand some brief exposure. This puts them on notice and in latter adventures when the GM includes "leaking atomic batteries" he can pre-decide what the severity of the exposure is and let the time element be determined by PC actions.

I am going with this last chart, it is a guide though, it allows me to make calls on the GW radiation and then fit to SF best, a level 18 really runs the range of 18, 17, & 16 on the chart based on how its specific effects are described in additional text on the critter. Like you I noted very few people survive after X amount of exposer or radiation illness over X days... so 30 seems very reasonable cut off, plus we got sci-fi drugs to give even worst case a chance all be it slim as this is Sci-Fi Smile

I linked the mutation rate to your ideas in the article, and followed your patterns so it has consistency with both your article & GD.

I am currently trying to knock out some sort of rough ball park figures for converting toxins from GW to SF... I thought there was a Giant Arn in GW, and I finally found it so I am rewriting the Arn paper to use that one instead of what I put in it but the Giant Arn has a poison stinger on it's tail... and I better get something figured out as poison is prety common in GW too.

Okay I worked up a gloss list for these conversions, GW toxins will take you down in 30 seconds as best I can figure in game time and all can be deadly depending on the PC...so I fiddled with the S nubers and made all T#s 5 I did not bother with ! as some can kill you by STA loss alone in SF... so here is my guideline 

03 = S5/T5

 

04 = S6/T5

05 = S7/T5

06 = S8/T5

07 = S9/T5

08 = S10/T5

09 = S11/T5

10 = S12/T5

11 =S13/T5

12 =S14/T5

13 =S15/T5

14 = S16/T5

15 = S17/T5

16 = S18/T5

17 = S19/T5

18 = S20/T5

 


This should allow me to be able to convert antidotes to SF as well.

I am working on all of this, trying to put together a big disease article... 

I have a several charts I am convertibg for use in creating random bugs, a few diseases that have been published to convert, and ideas about how refs can use disease in settings.
