A 1983 Dungeons & Dragons commercial has found its way to YouTube.
Back then, I couldn't watch that commercial without rousing my D&D jones, though it was false advertising to suggest that Jami Gertz might join your gaming group.
But watching it again, I'm reminded of what huge geeks those players were.
A lightning bolt cast by a magic user is five feet wide and 80 feet long in a straight line. Though it does 1d6 of damage per spellcaster level to the red dragon, half if a saving throw vs. spells is made, it also does the same damage to anyone else within the area of effect and can destroy their equipment. The only advantage to such a reckless tactic is that it can reduce your encumbrance.
