Fire shroud

Shroud of flame, also know as the TrollKill spell, is a fire-attack spell that causes a single creature to burst into flames. The target will stay aflame for at least a minute, though the flames can be disspelled or sumothered in water or another such liquid. The target loses all it's concelment and the flames may lash out at others nearby.

History
This spell first enters known Realmslore around 300 years ago, when the caravan master Muirhar Duskbrow found the Spellbook of Daimos in Bleached Bones Pass after a gnoll raid. Shroud of flame was one of the spells he found in that spellbook. The spell was slowy passed around to vairous wizards over the years. This spell was in the pamphlet Volo's Guide to All Things Magical(in Universe) and is known to be in Daltim's Tome of Fire.
