Hi, I killed the Don for the COC, but I did not go to the swamp first to get the Item from the Savant. The Savant was not at the swamp. What will happen when I go to get the Item from the Mook? Will I have to use force?

The savant will be at the swamp. Just go very close to one of the dark spots or a crack.

If the Don did not give you the AD when he died then you might be in trouble because it usually should be him who gives it to you, but the savant should still give you the item so you shouldn't have any trouble with the Mook.

Thanks for the info! I'll go wander around the swamp without avoiding those areas.

jk - keep in mind that you can get close enough to trigger the savant's appearance without actually getting so close that you trigger the explosive event that causes damage ;)
