You've entered the ranks of pit fighters in Tortuga. Survive three rounds in the Pit and reap a share of the winnings and a token of the Pit Boss's admiration.
- Survive the first round
- Survive the second round
- Survive the third round
You'll have only a few seconds between enemies to heal so try using combat medicine and first aid at the same time to heal as much as possible. Also, by removing any initiative-costing toggles between fights you can recover a bit more initiative. Be sure to use any other health, guard, or initiative regen skills (such as "second wind" for example) as soon as they become available.
