Armour and Shield for Monster Manual Men (and Women, Stan)

The monster manual helpfully provides a list of chances that various classes will have magic items. Unhelpfully, the categories used do not match up with the random tables in the DMG, making a random encounter with humans one of the most tiresome things that can happen to a DM playing wilderness encounters by-the-book. The problem categories are "armour" and "shield".

Here's those two classes of items split into groups using the frequencies from the DMG and without the cursed items.

Armour
For DMG-based campaigns just roll on the following table. For UA-based games, roll 1d6 and on 1-3, use this table and on 4-6 use the second table.
