D&D 5E Analysis of "Typical" Magic Item Distribution

[Quickleaf]

[MENTION=3424]FireLance[/MENTION] Thanks for the breakdown!

This seems like a very reasonable amount of magic for most campaigns. One potion (consumable) per level, and 5-7 magic items over the course of a level 1-20 adventuring career. Simple.

Interesting analysis. Has anyone already compared it to the treasures to be gained in the two published adventures?

Over the weekend, I entered the magic item tables and the treasure hoard generation tables in the DMG into a spreadsheet to determine what is the expected distribution of magic items that would be generated by what the DMG refers to as a "typical" campaign in the last paragraph of page 133, i.e. seven rolls on the Challenge 0-4 table, eighteen rolls on the Challenge 5-10 table, twelve rolls on the Challenge 11-16 table, and eight rolls on the Challenge 17+ table.

The number of rolls on the table are a very bad estimate and I'd ignore it. They don't come close to matching how many monsters you will be killing, and thus hordes you will come across, based on the XP requirements to level. For instance it's quite likely you'll be killing over 60 legendary monsters from 17 to 20, many of which are dragons and should each have a horde and you only end up with 8 rolls. This is why the treasure the published adventures is handing out is higher.

Keep in mind that this isn't something that's actually built into the math of the game. The game doesn't assume that the players will have this stuff, the tables and whatnot are simply there for those DM's who like the old style of rolling randomly for loot.

It is built into the math of the game and it does assume the players will have this stuff. Monsters requiring magic weapons for full damage are very common but they receive no penalty from having such a potentially powerful ability due to the fact that parties are assumed to be carrying the magic weapons to bypass it and only things like pets and NPCs will be losing damage.

What the math of the game doesn't account for is how much more powerful, even completely without magic items, a higher level party is, and doesn't work for them.

This analysis is very interesting, and highlights just how much players will rely on consumables over permanent items.

I find that items of defense are the most powerful, then offense...

If a PC fighter has +3 good armor and a +1 sword, or +3 sword and +1 good armor is very different.

It also plays different as other items come into play.

A wizard with a good wand or staff could double his spells per day at low level, and with two or three could totally change even mid level casters...

To translate this into a very even distribution of magic items over all 20 levels, I would probably go with the following approach:
1 common consumable every level from 1 to 5.
1 uncommon consumable every level from 6 to 10.
1 rare consumable every level from 11 to 15.
1 very rare consumable every level from 16 to 19.
1 legendary consumable at level 20.
1 uncommon permanent item at level 4, and another at level 7.
1 rare permanent item at level 10 and another at level 13.
1 very rare permanent item at level 16.
1 legendary permanent item at level 19.

This feels... off somehow.

I would go with the tiers actually used by the game instead of inventing new thresholds.

That is, replacing "every level from 1 to 5" and "every level from 6 to 10" with "every level from 1 to 4" and "every level from 5 to 10". A detail? Perhaps, but since you're doing statistical analysis I would expect you to adhere to the level bands actually used by your source data

For instance, instead of saying "1 legendary permanent item at level 19" I would go with something like...:

each player gets a 25% cumulative chance of getting "their" legendary permanent item from level 17, meaning that if they didn't get it by the time they reach level 20, the chance has reached 100% and they will get it at that level.

I understand that at level 19 the chance is greater of having gotten one, than not getting one, and that this is why you chose level 19. But it invents a new threshold, and means that level 17 no longer is the moment where you can start hoping for your item.

No.

Magic weapon yes; +3 weapon no, not a given at all.

You have been repeatedly told not to assume that the character is having a +3 sword. ANY magic sword will overcome magic resistance.

Simply stop it, Choc. If you feel the game breaks if you hand out +3 items, then don't.

I think the simple explanation is that magical items of varying rarity could be found over the course of a tier. In the 5-10 tier, for example, the PCs could find common, uncommon and rare consumable items. Hence, if you line up all the expected magic items by rarity and distribute them evenly, the rarity of the items will not correspond exactly to the tiers.

For instance, instead of saying "1 legendary permanent item at level 19" I would go with something like...:

each player gets a 25% cumulative chance of getting "their" legendary permanent item from level 17, meaning that if they didn't get it by the time they reach level 20, the chance has reached 100% and they will get it at that level.

There are, of course, many ways to inject more randomness into the distribution of magic items (including actually generating them as suggested by the DMG ), but the intent of this exercise was to establish what magic items a "typical" PC could expect to get, and at what level, similar to the wealth by level guidelines of 3e and 4e. And like those guidelines, individual groups could choose to follow them or ignore them as they wish.

i dont believe this kind of analysis is of any practical use. It's item roll averages compounded by "expected" hoard averages. Given the different experience/advancement methods available, I wonder how the devs even arrived at this number.

But regardless, once a game actually starts, and your players (and DM) begin to direct what happens, you can throw averages out the window.
