Mithral / Metal tower shield stats

[johnnymac]

Hey gang -

I know this has been discussed but I've never really seen a solid answer come down the pipeline.

We know that wooden tower shields exist and have their HP/hardness. There is also a magical item for a mithral tower shield.

What would be the HP on this mithral tower shield? We know its hardness is 15. With other metal equipment, the conversion for metal/wooden is pretty easy - but there is no "base" metal tower shield to convert from.

Has anyone else dealt with this? What are the stats for a "base" metal tower shield so that we can figure out other tower shields?

I know there is no solid answer for this - but does anyone have any examples of stuff theyve homebrewed? Specifically regarding the object HP of mithral/metal tower shields.

Thanks again

John

Light wooden shield = 7 hp
Light steel shield = 10 hp

Heavy wooden shield = 15 hp
Heavy steel shield = 20 hp

So roughly a third more HP for the metal version over the wooden version. Using that math:
Tower shield (wooden) = 20 hp
Tower shield (hypothetical steel) = 28 hp

Weapons and armor made of a special material only change their hp if the material specifically says it does (such as with adamantite).
