alchemically speaking, if you wanted a few strategically placed lumps/barrels of Kaboom💥 lining part of a cave wall to dissuade a red dragon from flaming in said cave, what options on Faerûn are likely to be chosen (esp if a dwarf & the war wizards are helping)? Oil-rich stone. Dwarves want this stuff gone from wherever they're mining because sparks ignite it, often explosively, and know where to find the nearest deposits…and war wizards can help with bulk transport (teleport or levitate) to the cave you'd like lined. ;}#Realmslore
