I'm not good at math... Can you tell me which factor or formula is used on the Level-Advancement table for Godbound? Or in other words, did someone have a table for Level 11 -> x?
I don't think there is a scale for it directly. If I was going beyond 10, I would just add the difference between 9 and 10 for the xp/dominion. Problem is that adding more effort/gifts/hp/attack bonus beyond 10 starts to break the system down. Same reason that all gift usage is capped at 10th level effectiveness, even if used by an NPC with greater hit dice.
Assume 3 XP = 1 session and simply divide the difference between levels by 3 to find out how many default sessions I thought it should take to go from level X to X+1. That's the only formula I used.
Sorry, but I don't get it... could you please give an example how you got the numbers in the table... And how do you got the Dominion costs, too?
Level 9 = 130 XP / 3 = 43,33334 period and Level 10 = 170 / 3 = 56,66667 period
There is no formula. The spacing between levels was simply a matter of me thinking about how many sessions it should take, multiplying that by three, and picking a nice-looking number that fit it. One session to get to level 2, two sessions to get to level 3, 32 sessions to get to level 9, and so forth. Dominion was simply eyeballed based on that and some rough assumptions for Dominion earned in play and via cults.
