It is hard to tell from this snippet, but I think the table letters correspond to rarity. These are mostly consumable items with some wondrous items thrown in. A/B are probably more of the same. Level 0-3 scrolls, +1 ammunition, common potions, bag of holding and so on.Is kinda strange, but maybe Table A /B contains an overall % of magic arms, armor and items.
I love random treasure tables. Reminds me of the treasure types by monster you used to get in 2e. My favourite treasure system by far. Hopefully the treasure entries for monsters say something like:
Displacer beast, lair. Gold 10d10+30. 20% table T (gems/art objects). 15% table K (magic weapons). 35% Table C (misc).
Bring out that DMG already!!!
Unfortunately, the most logical place to put that would have been in the Monster Manual. I agree, rolling up treasure in 2E was some of the most fun I had as a teenager.
... I was not popular in high school.
If you are rolling random items, it helps keeps the potential results from favoring one particular player.Interesting how potions, scrolls, ammo, and misc. magic items are appearing in the same tables. They crossed the streams.
If one is rolling for random items, it makes sure Consumable magic items still are given out. It also established that consumables are supposed to be a common treasure. For too long players have viewed consumables items as vendor trash to be sold off. Now that's thankfully not an option, it's important to make sure players get enough so they realize they're supposed to USE them.Having permanent items like portable holes, hewards haversacks, decanters of endless water on the same chart as a bunch of disposable items seems wrong to me.
