One on One: Flotsam is a side quest featured in Witcher 2 Assassins of Kings Enhanced Edition. The quest can be activated as soon as you enter Flotsam, but should be completed after By the Gods – Stringing Up Sods.
One on One: Flotsam is similar to Bring It On: Flotsam, meaning that you have to beat a series of challengers, but this time in fist fights.
To begin the quest, locate the scaffold in Flotsam and then the inn.
Follow the stairs down to the basement and enter through the door located on the other side of the corridor.
In one corner you should see some boxers. Near them is a character named Sheridan. Talk to him to activate the quest.
Geralt noticed what appeared to be a fist fighting tournament in the Flotsam inn.
He decided to test the abilities he had honed on dungeon guards. His first opponent was called Stycho.
When to start
After By the Gods – Stringing Up Sods
To win a fist-fight match you must complete a series of quick-events, by pressing the buttons that appear on your screen. For each quickevent Geralt will perform a hit on his opponent.
Note: Make sure you dont tap/mash the buttons. Press the button you see on the screen only once.
Your first opponent is Stycho, which is a weak fighter. After you defeat him, beat Fliparse, following the same rules.
The second fight is followed by a cutscene which introduces a new character, named Ziggy, who asks you if you wish to participate in a similar tournament, but for better prizes.
Note: A new side-quest, called Fight Club, is added to your journal; however, you should complete the current quest first.
The third fighter you have to beat is Tidy Tib, who seems to be a very powerful opponent. The rules of the game wont change, but to defeat Tidy Tib, you have to successfully complete multiple quick-events.
After you beat the toughest brawler, you will finish the One on One: Flotsam quest and you will receive a new diagram (Superb Leather Trousers).
Next, you should focus on the Fight Club side-quest.
