The Funky Ignition Lounge is a room. "This is where all evenings end." The stick of gelignite, the solid magnesium footstool, the vetiver candle, and the vodka bottle are here.
The burn description of the vetiver candle is "It burns right down, expensively but gothically."
The player carries an inexpensive firework. The description of the firework is "It is a cardboard tube with red and green stripes along the outside, and a fuse sticking out of the end." The burn description of the firework is "It ignites gloriously! You take a few hasty steps back in order to avoid burning yourself, and not a moment too soon. Red and green sparks fly out of the tube, and there's a whistling noise punctuated by several loud cracks."
The player carries a lighter. The description of the lighter is "You don't smoke, but you like to have access to flame now and then anyway."
Burning it with is an action applying to one thing and one carried thing.
Understand "burn [things] with [something preferably held]" as burning it with.
The block burning rule is not listed in any rulebook.
A thing has some text called the burn description.
Check burning something:
if the player carries the lighter:
try burning the noun with the lighter;
else:
try burning the noun with the noun.
Check burning something with something when the second noun is not the lighter:
say "Your trusty lighter is the best flame source available to you." instead.
