Walkthrough
When you reach the Heroes Guild you find the Guildmaster who was wounded while trying to defend the area. Speak with him and then go through the Guild Caves and into the Chamber of Fate to find Jack of Blades.
The battle begins once the cutscene is over, but you wont be able to hit Jack for now. First you need to kill all his Minions, preferably using the Slow Time spell, in order to make him lower his shield. As soon as the shield drops attack him with your sword.
Be aware that he is a good blocker, so try to use flourishes against him or the Assassin Rush to get behind him. When his health bar is half he abandons the melee battle and he goes in the center of the chamber from where he shoots various projectiles at you.
Fortunately, rocks are emerging from the ground and you can use them as cover between his attacks. Stand behind a rock and charge your bow (Multi Arrow is a great spell to use during this part of the battle), then shoot Jack when he takes a break. You have to be fast, so you might want to use Slow Time to gain an advantage.
Depending on how fast you hit him and on the power of your attacks, he may not even have time to spawn more Minions to help him. They are annoying when you try to hit Jack, hence its a good idea to summon a creature to lure them away.
After you defeat Jack of Blades your sister wakes up and she gives you a choice. You can either take the Sword of Aeons and kill her, or you can throw the sword in the vortex.
It is obvious which one is the Evil choice and which is the Good choice, and once you decide what to do you complete the quest. However, the story of Fable Anniversary does not end here.
