Mechanics (5e Fallout Supplement)

Getting started

Congratulations! Vault Tech welcomes you to join us in our new Endeavor. The "Vault Tech 5e Supplement" will guide you through simulating various possibilities of the world outside your patented Vault-Tech Vault! There are a handful of additional rules one must keep in mind:

  • Radiation
  • Bleeding (activates on all damage types except energy).
  • Infection.
  • Critical Hit Table.
  • Stacking Advantage.
  • As magic generally does not exist in this setting, Arcana is used to determine one’s ability to maintain, repair, and mechanically control weapons and other machinery, such as terminals or robots.
  • You regain 1/4 of your hit die maximum at the end of a long rest.
  • Being prone only grants disadvantage on attack rolls that are made against creatures within 10 feet.

Critical Hit Table

When you score a critical hit on an attack roll, you must roll 1d10, taking the respective result. Mechanics that have (+/-X) means that you can make a DC 15 Medicine check once per hour. On a success, the DC and effect decreases by 1. Once this has happened X amount of times, you no longer suffer from the effect. Certain effects have unique results if they happen more than once. If a result has a slash, flip a coin and call the result while it’s in the air. On a successful call, the effect is cured with one use of a doctor’s bag or 5 successful DC 15 Medicine checks that can be made once per hour. On a failed call, the effect becomes permanent.

gollark: Yes, but you can use it for, well, querying things, which is a thing applications often do.
gollark: I feel like you would mostly be better off with JSON and separate schema formats, or maybe GraphQL.
gollark: It's verbose, *never* gets used sanely, makes attributes and... other things? distinct for some reason...
gollark: XML is ææææææææææææææææææææææ.
gollark: It doesn't look very listy. It looks like a generic unquoted string.
