D&D General An interesting talk with AI (creating an EXP table)

[ezo]

My prompts follow, the results from the AI are in quotes:

PROMPT: Give me an experience point progression from level 0 to 12, starting at 0 experience points, and ending at 250,000 experience points, like would be used in a role-playing game such as Dungeons and Dragons. The progression cannot be linear.

Here’s a non-linear experience point (XP) progression from level 0 to 12, starting at 0 XP and ending at 250,000 XP. This curve uses a progressive exponential growth with slower gains at lower levels and steeper gains at higher levels—typical of many RPG systems like Dungeons & Dragons:

Level	XP Required
0	0
1	300
2	900
3	2,700
4	6,500
5	14,000
6	23,000
7	34,000
8	48,000
9	64,000
10	85,000
11	120,000
12	250,000

This progression loosely follows an exponential curve with a sharper jump between levels 11 and 12 to reflect the significant leap in power or narrative impact typical in many RPGs.
Would you like a graph or chart of this progression?

PROMPT: This progression is nearly identical to the progression in 5E Dungeons and Dragons. I want a progression which requires more experience points at lower levels so there is not a huge jump at the end.

Got it! You want a more front-loaded XP progression—meaning early levels require more XP than in standard 5E D&D, and the jump to higher levels is smoother and less drastic. Here's a custom progression that spreads the 250,000 XP more evenly across all 12 levels, using a curved but decelerating growth:

---

Custom XP Progression (Level 0–12, Total XP: 250,000)​

Level	XP Required (Cumulative)
0	0
1	10,000
2	20,000
3	35,000
4	55,000
5	80,000
6	105,000
7	130,000
8	155,000
9	180,000
10	205,000
11	225,000
12	250,000

How This Differs from 5E:​

• Early levels take more time: You start off needing 10,000 XP per level instead of just a few hundred.
• Progression smooths out later: The jump between levels becomes more gradual as you go up.
• More balanced feel: Good for campaigns where you want early adventuring to matter more and high levels to be attainable without a huge late-game XP spike.

Would you like a visual chart or formula to customize this curve further?

PROMPT: Yes.

Here's the chart showing your custom XP progression. You can see how the curve rises quickly early on and flattens out toward the higher levels—perfect for a campaign that wants slower early growth and a smoother transition into high-level play.

Want help tweaking the curve further or turning it into a formula for future levels?

PROMPT: Modify the progression so there is less experience in the middle, creating a curve that is more parabolic and not linear.

Here's the updated XP progression with a parabolic curve—it grows slowly at first, levels off slightly in the middle, and then ramps up again toward higher levels:

---

Parabolic XP Progression​

Level	XP Required (Cumulative)
0	0
1	1,736
2	6,944
3	15,625
4	27,777
5	43,402
6	62,500
7	85,069
8	111,111
9	140,625
10	173,611
11	210,069
12	250,000

---

This makes the middle levels easier to attain compared to a linear or exponential system, giving your campaign a smoother midgame while keeping early and late levels more significant.

Would you like this turned into a reusable formula or table for more than 12 levels?

PROMPT: This is very close! Now, modify the numbers so experience points required are in multiples of 250, for example, at level 1 it would be 1750 instead of 1736.

Here's your final version of the XP progression with all values rounded to the nearest 250 for cleaner milestones:

---

Final XP Progression (Rounded to Nearest 250)​

Level	XP Required (Cumulative)
0	0
1	1,750
2	7,000
3	15,500
4	27,750
5	43,500
6	62,500
7	85,000
8	111,000
9	140,500
10	173,500
11	210,000
12	250,000

This curve has a nice parabolic shape, with early and late levels requiring more XP and a smoother middle game—plus, all values are easy to track at the table. Want a printable version or spreadsheet file?

And there you go.
