How to keep Sir Radvic's sword after Ruined Skaliz sequence.

[Kai]

When you are in the dream sequence, navigate around your parent's corpse into your family home and open the chest and drop your stuff in there, including the Sir Radzic's sword which became a non-quest item and is a equippable and sellable item.

Now when the game starts, simply fast travel back there and pick it up. LOL!

Now using this apparent hole in the game's design, you can leap over a wall, leave the map area without triggering the Cuman chase sequence.

Head far south enough to avoid possible 'deadly' death arrow walls, then circle around to Sasau then Rattay then Thelmbar if you'd like, as long as you reach the town, it will trigger part 2 of the chase sequence.

From this point on you lose the horse so never keep anything on it, if you want to stow stuff, stop by Rattay's Miller house and drop stuff off in the player chest since it gives you permission before you even get there, or any inn for 2 coins.

Then when you get to the town where Sir Divish locked you in, play through this part and escape, then go to Skalitz, going towards the farm area to trigger the Cuman chase sequence, inside Ruined Skalitz area. There is no death wall and you spawn your horse back with you again, this time it stays with you for good.

To finish this sequence and start the game for real out of prologue, walk to your parents, don't ride the horse to them or it will bug out the game and cause a infinite loading screen (since the cutscene uses Henry's model to walk up to the parents' corpses, it gets confused with you on a horse)... Also avoid having the Cumans enter the town and be nearby when you do this sequence, so try to kill them off btw as you can lure them to guards in towns and stuff...

Remember too that when you activate Part 1 of the sequence, you start bleeding and is low health again, so bring bandages and find a hiding spot, then kill your pursuers in order to stop them as they can chase you to the ends of the earth if they so wanted to.
