Burning Leaves will automatically be added to the campground every ascension (where applicable, i.e. not every campground in every special challenge path will have it)
Having Burning Leaves will allow inflammable leaves to drop after combats.
You don't feel like burning that many leaves again today.
Throwing a non-special number of leaves on the fire gives the following messages.
From 1 to 10, you will get an unqualified message, e.g. "roars louder". From 12 to 110, you will get "a bit" messages, From 112 to 1110, "quite". And from 1112 onwards, "way".

Value must be less than or equal to X.
It also means you can't even input text. Pressing a key which would result in a non-numeric character does nothing.
You can, however, input a dot, the letter "e", two pluses or two hyphens. What other combinations of these characters are allowed is left as an exercise for the reader. Pressing the "Burn Them!" button then gives the following:
Please enter a number.
Choosing the "Jump in the Flames!" option grants the "Aura of Fire" effect, the length and power of this effect is dependant on how many leaves are currently burning:
You jump in the blazing fire[sic] absorb some of the flames and jump out. Stronger, faster and better.
