Lightning damage is one of the five damage types and is one of the three types that count as elemental damage. Landing a critical strike with a skill that deals lightning damage inflicts the shock status ailment. Lightning damage is mitigated by lightning resistance and reduction to lightning damage taken. The 25 damage is first reduced by 5 and then halved, so the creature takes 10 damage. Multiple instances of resistance or vulnerability that affect the same damage type count as only one instance. For example, if a creature has resistance to fire damage as well as resistance to all nonmagical damage, the damage of a nonmagical fire is reduced.
If you know your house has just been hit directly by lightning, call the fire department. It is common for lightning to start fires in the attic and within walls of homes. These fires inside enclosed spaces may not be visible in their beginning stages.
A cloud-to-ground lightning bolt's main objective is to find the path of least resistance from the cloud to deep into the ground. Most houses are filled with many potential routes for lightning to follow in its journey. Canon pixma mp480 software download free for mac windows 7. This can include gas and water pipes, electric lines, phone lines, cable TV/internet lines, gutters, downspouts, metal window frames - anything conductive in a house is 'fair game' for the lightning to follow. Lightning doesn't need conductive objects to reach ground, however - it's just forged its way through miles of air, so conductive objects in a house are a mere 'convenience' that it will use if they are available.

A stroke of lightning forming a line of 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw.

Lightning passing through a house will often 'branch' and utilize more than one path to ground at a time. It can also jump through the air from one conductive path to another in what is called a side flash. For example, lightning may first connect to electric lines in the attic of a house, then jump to better-grounded water pipes on the first or second floor. Lightning can connect to gutters, then jump to a window frame as a 'stepping stone' to the electrical system or water pipes. All or part of bolts have been seen jumping from wall outlets to sink faucets and even across rooms!

Lightning current will produce significant damage to a house that is not equipped with a good protection system. Professionally-installed lightning protection systems are expensive and the risk of a direct strike is low, so most homes do not have them.
Lightning presents three main hazards to a house that is hit directly:
What can you do to stay safe from lightning while inside of your house?Since we know the common paths lightning can follow in a house (wiring and pipes), the best thing to do is stay away from those paths as best as possible during a storm. Direct contact with them should be avoided. This includes taking a shower or bath, washing hands, doing dishes, typing on a computer, playing video games and using a wired phone, tool or appliance. Metal-framed windows should be avoided. Wireless devices are safe to use (cell phones, cordless phones, remotes, etc).
Direct skin contact with earth ground should also be avoided, as lightning current can travel through soil and across wet/damp concrete. Wear shoes if walking in a basement, garage or patio.
What to do if lightning strikes your houseIf your home is hit directly by lightning, your immediate concern should be for any fires that may have been ignited. Call the fire department!

Can you get struck by lightning inside of a house?
While it is rare, yes, it is possible to receive a lightning injury inside a house. Burns and electric shock injuries can occur when someone is in direct contact with one of lightning's chosen paths to ground. The most common indoor lightning injuries involve a person talking on a corded phone or resting on/looking out of a metal-framed window. 'Side flashes' (discussed above) that jump across rooms can also cause injuries, but are very rare. Indirect shrapnel-related injuries from building materials have also been documented.
How to protect sensitive electronics from a strike
It is nearly impossible to provide 100% protection to sensitive electronics from a direct lightning strike. The best thing to do is to unplug any high-value item you wish to protect during storms, as surge protectors and UPS units can't provide direct-strike protection. Some could argue that the risk of a direct strike to any given house is too low to justify unplugging everything for every storm that passes overhead. It's wise to make sure your homeowner's or renter's insurance covers lightning damage. Your insured expensive electronics can be replaced, after all. However, consider irreplaceables such as the data saved on your computer (photos, videos, work files, etc). You can mitigate that risk by performing frequent offsite backups and/or storing data on an external hard drive that you can unplug when needed.
Should I have a lightning protection system installed?Animation showing how a lightning protection system works
A professionally-installed and well-grounded lightning protection system will reduce or eliminate the fire and injury hazards if your house happens to be struck directly. You will want to assess the risk of a strike and weigh the costs versus benefits. Insurance may be a more cost-effective option, especially if you live in an area of average to below-average thunderstorm frequency. If you are located in a zone if frequent lightning activity (such as Florida and the Gulf Coast regions of the USA), a protection system may offer more of a benefit.
