The Thieves of Waterdeep
Oil of Firey Burning
inflicting 5d6 points of damage to any creature directly exposed to the substance (save vs. spell for half damage). If hurled, the flask will always break. Any creature within 10 feet of the point of impact (up to a maximum of six creatures) will be affected. The oil can, for instance, be used to consume the bodies of as many as six regenerating creatures, such as trolls. If the flask is opened, the creature holding it immediately suffers 1d4 points of damage. Unless a roll equal to or less than the creature’s Dexterity is made on 2d10, the flask cannot be re-stoppered in time to prevent the oil from exploding, with effects as described above.
