Conversions
When converting B/X-derivative material to Vagabond, keep these guidelines in mind.
No "Save or Die"
Vagabond discourages insta-death mechanics that can spring up on Heroes without warning. When presented with a "Save or Die" mechanic in a B/X-derivative material, allow the Hero subjected to it to instead take 1 Fatigue.
Economy
Vagabond uses the Silver Standard for determining the value of Items. As such, the currencies break down as follows: EXCHANGE RATE
Armor
DRD
Gold Standard Conversion
Some tabletop games use the Gold Standard. Should you want to convert from Gold Standard to Silver Standard, use the following table: GOLD STANDARD CONVERSIONS Should you think of something you want to purchase or craft that isn’t accounted for in the rules, you can estimate the value by converting the real-world price into silver at 1s per $1 USD.
Armor/Armor Class
Armor is handled as Damage Mitigation (Mit.) in Vagabond. To determine Armor Class for other systems, use the following table. The equation to Vagabond from Ascending AC is ((AC - 9) / 2.2), round down. AAC DAC 10+DEX 12+DEX 11+DEX 13+DEX
