Ok I was going to say something else but I see why this needs to be a lua mod since the jsons only allow for skill descriptions and not the addition of new skills at least not in that way. Now on that note I really like the idea of athletic the other traits look good too.

With the achievements, would a highscore list be doable?

How long should I expect the athletics skill to go up?

athletics should be practiced by 1 point per 10 tiles traversed, but for at least 1 point.
```auto
local squares_per_train = 10 --TODO: make this variable configurable or implement some smarter formula for `trained_amount`
local trained_amount = squares_walked_delta / squares_per_train
if (trained_amount > 0 and trained_amount < 1) then
trained_amount = 1
end
MOD.PracticeSkill("athletics", trained_amount)
```

Love the nightmare mod, I like the idea of showing a visualization of my characters night terrors. I hope you add more additions to the nightmares so I can see cool new horrors to be explored while dreaming!

[code]
local squares\_per\_train = 10 --TODO: make this variable configurable or implement some smarter formula for `trained_amount`
local trained\_amount = squares\_walked\_delta / squares\_per\_train
if (trained\_amount \> 0 and trained\_amount \< 1) then
```
trained_amount = 1
```
end
MOD.PracticeSkill(“athletics”, trained\_amount)
[/code][/quote]
Actually if say I think the lua failed to load or something like that what would I do to try and re activate the lua. I ask cause since I first used it on a save without it causing an aparantly critical load failure it gave an error but it did not show up any more later. Anyways I ask because I have literally walked miles and athletics did not tick once. Maybe I need to turn them off and back on again.

There is some initialization which is done on new player creation - some zero values are being saved withing the player.
PARAM.save(“squares\_walked\_total”, 0)
PARAM.save(“stats\_squares\_walked”, 0)
PARAM.save(“speed\_bonus”, 0)
If you add mod to existing save you can try to run these statements in debug lua console.
You can also can provide error text/screenshot or provide savegame, so I could check what’s wrong.

data/mods//dda-lua-skills/main.lua:147: attempt to perform arithmetic on a nil value (local ‘squares\_walked\_prev’)
That is the error I got when I tried those commands you gave.
EDIT:never mind skill is increasing and my current speed is now 102 so huzzah.

Just added atomic flamethrower which bursts fire in selected direction. Works best with realtime progression turned on.
