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 (cauterized with Burning energy).
• 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. Critical Hits 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. Effects 1, 2, 3, 6, and 8 can be cured with a single use of a doctor's bag(no ability check required). Certain effects have unique results if they happen more than once. All these effects are dealt to the enemy whom was damaged.
