Murder, Arson, Destruction of property, Trespassing.
The Arsonist is one of most deadly roles in the game when left unchecked for an extended period of time. The role has the ability to douse a target in gasoline. A later night he can ignite all his doused targets, killing them.
As the Arsonist, you want to try and douse and kill those that aren't about to be killed. These are generally the players who are receiving the least amount of attention.
A Town leader, such as a confirmed Sheriff can be a good choice to douse since the Doctor may be protecting the Sheriff from death. Ignition is normally unaffected by healing.
The longer the Arsonist waits to attack, the more deadly the attack will become. It is often best to wait as long as possible before attacking, but every day you'll be gambling that your doused targets won't die at night and that the Town won't lynch you.

If there are multiple Arsonists in the game when one Arsonist ignites it will burn the players doused by both Arsonists.
If the Arsonist performs no action at night it will undouse the Arsonist if he is doused.
The Witch cannot stop the Arsonist from igniting his targets. However, it can cause the Arsonist to ignite despite that it is dousing someone. This is caused by making the Arsonist target himself.
If the Arsonist gets doused, he will receive a message telling him so even if the "targets are informed they are doused" option is off.
However, if the Arsonist becomes a Cultist, he will never know if he ever gets doused after the conversion. Furthermore, he loses his ability to undouse himself.
Multiple Arsonists can win together.
If an Arsonist is attempting to undouse himself and he is bus driven the night he undouses himself, the person he is switched with will be undoused instead of the Arsonist.
