The Force

Below is a list of d20 Force skills and feats, and (as near as I can tell) the WEG equivalents. Note that not all d20 feats/skills will have equivalents, and these are listed as n/p (no parallel). Some of those without parallels have been converted, and should be made available here. In one or two cases, a Force power that I've created for my own campaigns fits the bill for a cross-over, and these should also be available.

Converting Force skills and feats into D6 isn't too difficult. By and large, Force skills in d20 are quite similar to the Force powers used in D6. Feats, on the other hand, are somewhat different, in that some Force feats represent learned powers (Control, Sense, Alter, and Force Lightning, for example), while others merely affect the way that Force users in d20 operate (ie, Force Mastery and Prolong Force).

The feats that affect the way Force users operate in d20 aren't compatible, though they might grant a bonus of a pip or two to one or more Force skills (if converting a character from d20 to D6). The rest of them, however, are more than easily translated over to D6, and the majority of them are standard powers.

To determine the levels of a D6 character's Force skills, start them out with 1D each in Control, Sense, and/or Alter (whichever ones that the d20 version of the character has). Increase these by 1 pip each for every 2 ranks they have in an associated Force skill. Divide these pips evenly between Control, Sense, and/or Alter if the Force skill in question converts to a power that uses more than one, and round fractions up. For example, Force Grip converts to Telekinetic Kill, which uses all three Force skills in D6. If a d20 character has Force Grip at +6, his D6 counterpart would gain the Telekinetic Kill power, as well as +1 to each of his Force powers (6 ranks = 3 pips, divided three ways). If the number doesn't divide evenly, assign the remaining points in the following order: Control, Sense, and Alter. For example, if, in the previous example, Force Grip was rated at 7 ranks (7 ranks = 3.5 pips, rounded up to 4 pips total), the bonus to the D6 character's skills would be Control +2, Sense +1, and Alter +1.

In the case of Force feats, award a +2 bonus to each related D6 Force skill for each Force feat possessed (with the exception of the Control, Sense, or Alter feats, which actually give the D6 character those Force skills at 1D apiece). For example, Dissipate Energy (d20 feat) translates to the Absorb/Dissipate Energy power in D6. Absorb/Dissipate energy uses Control, so apply a +2 bonus to the D6 counterpart's Control skill. If the feat's corresponding Force Power uses more than one D6 Force skill, apply a +1 bonus to each.

In a few instances, I've found that d20 characters will possess Force powers that require a D6 Force skill that they would not possess. For example, in d20 the Enhance Ability Force Skill does not require the Control feat, while it's corresponding power in D6, Enhance Attribute, does. In such a case, go ahead and give the D6 version of the character the Control skill at 1D. It's sloppy, but it gets the job done.

Though it's probably a big pain in the butt, try to ensure that a converted character has all the required prerequisites for his new Force powers. If the character doesn't have them, you can choose to either not worry about it, or you can give him the required powers with no further bonuses to his Force skill totals.

Droids

Just like for humans, except that stock droids get +1D to each skill for every 2 ranks the d20 version has. As an option, use any unspent points (listed with the d20 stats) to buy extra pips and place them into necessary skills. Optionally, convert them as you would any character.

If the droid is not a "stock" model (ie, it is an experienced character), convert it just like you would any other NPC, with each rank in a d20 skill equating to +1 pips in D6.

Droids convert in a manner similar to characters, with some exceptions.

Stats: This can be tricky. Convert attributes just like you do for characters, but be aware of the final point totals. Droids don't translate right across really well, at least not in a way that I'm completely comfortable with. As a rule, I round pips on the final stats up or down – 2D+1 becomes 2D, and 2D+2 become 3D. Also, consider the droid's function when converting stats. A droid designed for combat is unlikely to have a high Technical attribute, even if its d20 Intelligence score is 18.

Feats: Just like for humans.

Droid Equipment: Determine effects on a case by case basis.

Ships

What follows is a piece-by-piece method of converting ships from d20 to D6. You don't really have to go in any particular order, just do things as they pop up.

Crew Skill(s): Figure out the base dice pool for the skill(s) in question by converting the listed rating (which, in d20, is generally a Crew Quality description). "Untrained" gives a base of 2D, "Normal" gives a base of 4D, "Skilled" gives a base of 6D, and "Expert" gives a base of 8D. Modify this number as you see fit.

Hyperdrive Multiplier: Converts right across.

Nav Computer: Generally "Yes" in the case of larger ships. In the case of small fighters, they're only good for one or two jumps worth of coordinates, unless they have an astromech, in which case they can store 10 jumps.

Maneuverability: This is tough, since d20 doesn't use a parallel. Using common sense and the existing ships as an example, choose a rating that fits the concept of the vessel (examples: A-Wing: 4D, TIE Interceptor: 3D+2, X-Wing: 3D, Y-Wing or TIE/In: 2D, B-Wing: 1D+1, Z-95: 1D, YT-1300: 0D).

Speed (Space/Atmosphere): This is tricky, too. D20 has only five speed ratings, and they don't seem to correspond with D6's speeds. Again, you need to compare the ships to the old ones (examples: A-Wing: 12, TIE Interceptor: 11, TIE/In: 10, X-Wing: 8, Y-Wing or Z-95: 7, B-Wing: 6). Atmospheric speed can be found on the chart on page 129 of the SWD6. You might also consult the following:

Star Wars d20 Ship Speed	Star Wars D6 Ship Speed
Stop	0
Docking	1
Cruising	2-6
Attack	6-8
Ramming	8 or more

Concerning Existing Material

I don't intend to convert material unless it has never before existed in D6 format. In my opinion, the original statistics as printed in the WEG products will have precedence over the newer d20 incarnations. I will, however, attempt to let you know where the original D6 material can be found, or I may (in some cases) list the original D6 stats all by themselves. If you require stats for a specific entry that I have referenced to an existing WEG product that you do not own or cannot lay your hands on,
