The fumes that were generated (chlorine trifluoride, hydrogen fluoride, chlorine, hydrogen chloride, etc.) severely corroded everything that was exposed.3 One eyewitness described the incident by stating, “The concrete was on fire!” The ClF3 dissolved the 30 cm (12 inch) thick concrete floor and another 90 cm (36 inches) of gravel underneath the spill. However, the dry ice bath embrittled the steel container wall, which split while it was being maneuvered onto a dolly, instantaneously releasing 907 kg (2,000 lb) of cold ClF3 liquid onto the building floor.
The container had been cooled with dry ice to perform the liquid transfer and help make the product safer to handle, since the ClF3 vapor pressure would only be about 0.007 kg/cm2 (0.1 psia) in the subcooled state. My favorite story about a spill.Ī major incident involving ClF3 occurred the first time a one-ton steel container was loaded with liquid ClF3 for bulk shipment. Its fun to read about but I would never go near the stuff.
Inspiration: chlorine trifluoride is scary as FUCK.Īgreed on how scary ClF3 is. This is a *brutal* boss - the only saving grace is that it's based on an adult dragon rather than an ancient or greatwyrm (and that I am not super tactical). Its breath weapon gives a week-long debuff, giving a level of exhaustion every day until treated with greater restoration as it dissolves the victim from the inside out. It's got aoe melee attacks, a spammable ranged attack that damages mundane gear, minion summoning, a weakness that can be discovered by research, and a videogame weak spot, and regeneration until that weak spot is destroyed. Soo yeah, it's a big fuckoff dragon that is a battlemaster/gloomstalker, which means it's invisible in darkness, can throw PCs around the battlefield, and gets an action surge and second wind. As the clerics tended to him, his final words before succumbing to its caustic poison were a warning: stay away, unless ye be very brave, very skilled, and very stupid. It has the horns and scales of a black dragon, they described, with veins of fire all along it and a maw like an hot forge, its flames burned sand and dirt and stone, and it gave its name as Liivagol. That the briars opened like the devouring maw of the abyss to welcome the dragon after it slew their party's paladin. That their party's wizard had attempted to teleport them inside its lair but they were violently shunted into an open plain in the shadow of the mountain, their wizard dead from the backlash.
Returning haggard to civilization and bearing the rusted, charred, and pitted armor of their companion, they told of a great mound of briars in the mountainside above a kobold stronghold. Only one person has believably witnessed the dragon and lived. Soon, legends rose of spontaneous conflagrations on moonless nights, clouds of death left behind that burned and dissolved their victims from within, and a lingering dread within the echo of massive leathery wings, as this invisible horror wrought destruction upon the kingdoms of mortals. One such black dragon bound a sliver of the elemental plane of fire into his brow already skilled in combat, he became an embodiment of terror. Being closely attuned to elemental magic, they can produce powerful mutations within themselves by absorbing great sources of elemental magic.
Yet for some dragons, this is not enough, and they seek greater power still. Liivagol The Caustic Phoenix, Mountain-Killer, He Who Burns What Cannot Burnĭragons, in even their common forms, are formidable foes.
