Use chart found on page 111 of Player Handbook for standard classes. For any non-standard class, check with me or read the book that class came out of, you can find their base gold.
If dice roll less then the value in parenthesis, then use the given value for gold.
If you choose to use Dvati as your character’s race. Roll for gold as usual, but add 50% of diced value. As you will need to outfit two bodies, not just one. So for a Dvati Ranger, you would be rolling 5d4x10 (125 gold), so you would roll 5d4x10+50% (125 + 50% = ~190 gold)
