If you think someone is going to put a Hit out on you, you can pay Cash, Stamina and Energy to set up a Rigged Ignition.

The trap will fire the next time they try to Hitlist you, killing them instantly!
Every player has a base price you must pay to set an Rigged Ignition, which is determined by their income. If the player's income increases, so does the cost to set a Rigged Ignition.

If someone is placing more Ignitions and Hitlists against you than you have placed against them, then the Ignition price will decrease. There is no hard limit on how far this price can drop. Only Hitlists and Rigged Ignition actions influence the cost, other aggressive actions have no effect on the amount paid.

It's important to note that you cannot get off someone's Rival Record by dying via a Rigged Ignition — once you heal back up, your Rival will still be able to attack you normally, even if you are outside their normal level range, until the 24 hour period expires (assuming you don't continue to hit them back, which would extend the timer.)
To set a Rigged Ignition, navigate to a player’s profile, and hit “Defend”.

An option to set an Ambush or Ignition will pop up.

To manage your existing Ignitions, navigate to the “Home” tab, then “Rival Mobs”

Then, click the “Ambushes and Rigs” Tab.

From here you can review and delete your currently set Rigged Ignitions.
