1001+ ways to screw with your DM/Party

[Xaroth]

The feat and weapon property keen do not stack.

By not stacking, are you meaning Improved Critical and Keen would only grant a total of 6 extra numbers rather than nine? If so, I know that already.

*begins trying to explain*
*stops*

Okay, I've confused myself now.

Improved Critical applied to a Scimitar makes it go from 18-20 (3 numbers) to 15-20 (6 numbers). Disciple of Dispater's Iron Power +2 stacks with Improved Critical, but not with Keen. Keen is just an extra 3 numbers. So without Keen that should be... 3-20 (18 numbers)? And Keen would make it 0-20, but since a 0 isn't possible, it's a 1-20.

Weapon Master (Kensei) 7 wouldn't even be needed.

I'm so confused right now.
