Nnjsword "Flashbangs" "Flashbangs" are grenade-like weapons used by many counter-terrorist groups, including related groups like the DEA. As far as I know, they emit a bright flash, and a loud "bang" much bigger than a human can handle, temporarily disrupting the nervous system until the insertion team can move in and arrest hostiles, and safeguard hostages. The flash emitted does not produce enough heat to burn anything, as I understand it. Since this weapon exists, what effect would a high amount of candelas, and/or decibels have on a vampire or related creature susceptible to sunlight? How about Zombies? Maybe zombies are constantly in a daze? Alucard Tepis That depends, really, with regard to which mythos your particular vampires and or other undead belong to. Some say that vampires are vulnerable to ultraviolet radiation, so a million candle-power incandescent lamp may not do nearly as much damage as a decent tanning lamp. Others say that it is the "holy" light of the sun that does the damage, so no artificial light, short of one powerful enough to set them on fire (which has its own problems for vampires) can harm them. With regards to sound, if you happen to be up against a Stokerian vampire, which tend to be a bit...squishy, or a particularly decrepit zombie, then an extremely powerful sound wave may cause significant damage. On the other hand, if you were anywhere near when it went off, it would likely do considerable damage to you as well. I am reminded of one Kindred's comment, "If I were to shoot you with silver, jam a stake in your heart, chop your head off, and set you on fire, you'd be dead too!" While the sensory acuity of zombies is legendarily poor, so a sensory-overloading weapon may merely make them temporarily even more inaccurate, some vampires are known to have quite accute senses. Even moreso were you to talk about one of the lycanthropic species. So, in that case, a flashbang might be helpful to simply distract them long enough to deliver a deathblow or escape.
