Weapons with alternate modes

[beniliusbob]

Let's say I want to use a morningstar with a shield. Does it use my one-handed or two-handed WPF?

Also, does anyone have a list of all the "two-handers" that can be used with a shield? Is there any nerfing to the weapon when you do this, like how polearms deal less damage when used with a shield?

A 2h with a shield uses 1h WPF, and like polearms it has a 30% reduction in speed and damage.

Bastard Sword and Heavy Bastard Sword can be used with a shield. Not sure if any other 2h weapon can be used with shield.

Also longsword and katana.
