Back again with a little something I've been working on. My math skills and remembrance of repair/trading rules tend to leave me on the fly, so I made myself a little excel calculator to help and thought I'd share.
The Repair bench will determine the repair cost based on the item's original value (which you input) as well as it's current damage level, less any discount for advantages rolled.
The Trading outpost initially will calculate the difficulty based on the item's rarity, plus/minus and modifiers for the type of planet the player is currently on. Also have a section to put in the item's base cost with a "suggested" price based on the planet less any net successes.
Feel free to provide feedback and point out any flaws in my understanding of the rules!!
