D&D 5eStar FrontiersThoughts & Things

Star Frontiers / D&D 5e Conversion Part 2

So here is the continuation of my Star Frontiers conversion using Dungeons & Dragons Fifth edition core rules.  I’ve been tweaking things, and pulled the equipment side out of the character creation.  I created the Astronaut class, and changed the races features a bit from some great responses I received.  So I am breaking this up a bit, and I hope you like what I am working on, and since I made Psionics a character overlay that can go with anything, Psionics can easily be added to the Star Frontiers world. I’m going to start working on vehicles and robots, and will update these pages as I hear back from all you cool people.  Please let me know if I goofed somewhere, or if I could make it better.

Star Frontiers


All the costs are in credits. Use the list of weapons in the PHB for Archaic weapons.  Follow the class proficient weapon skills for those archaic melee and ranged weapons.  You are usually issued weapons from your employer to accomplish missions, so don’t look into this cost thing too closely. Unless you are paying it back to an employer because you broke his stuff.

Advanced Technology Weapons

I started with making the lasers do fire damage, sonic weapons cause thunder, needler’s are definitely piercing, and grenades and rockets create bludgeoning and piercing damage.  And needler weapon ammunition can be changed out so that is why they are listed twice.  It would take an action to change out.

Sleep property causes a chemical induced sleep on all known creatures. On a failed Constitution save versus DC 15, the target is rendered asleep. Sleep continues for up to 1d4 hours, or is given a stimdose injection.
Grenade weapons have a blast sphere of 5 from the target that may not include a creature.
Rocket weapons are similar to grenade weapons but have a blast sphere of 15.

Advanced Technology Defenses

Only one suit and one screen can be worn at the same time. I made power screens so that they are an additional defensive barrier.  Archaic armor can also be worn with screens, but then a Defense suit can not be worn.
Power Screens
I didn’t want to over power (OP) the Power Screens so I limited their use. Power Screens use an reaction to turn on and will stay on for 10 minutes after switched on, can’t be turn off. They can be recharged, but takes 1 hour.

Defense Suits
The Defense suits behave just like Archaic Armor, except extremely light and durable.  The Civilian skeinsuit appears to be look like civilian attire, while the Military Skeinsuit has a changing camouflage design that increases Stealth+6.  The Flak armor is lightweight polymer armor that has interlocking plates over your clothes.
