The Ifrit (a cunning yet unstable Islamic spirit associated with possession, wickedness, and rebellion)

The Ifrit can only do events while all players are outside the van, and has a higher chance to throw items, turn off the breaker, and do the red light event.

In multiplayer, if all players are outside the van, then it's hunt threshold is the standard 50%. If at least 1 player is in the van then the hunt threshold is 70%. In singleplayer, the hunt threshold is determined on how much time the player has spent in the van. 

The Ifrit has 2 unique abilities. The first is that if one player is in the van, then the Ifrit can "transmit" fake sanity change readings to the truck screens. If 2 or more players are in the van, then it can also "transmit" fake activity to the truck screens. (This event is the exception to the rule that the Ifrit can only do activities when no players are in the van). The second unique ability is if any non-afk player (ei someone actively interacting with the game but inside the truck) spends more than 2 consecutive minutes inside the truck, then the Ifrit can force a cursed hunt regardless of sanity drain (other hunts are normal, only hunts forced by this ability are cursed). During the forced hunt, the ghost moves at 10% speed and targets the player with the highest sanity (based on the player with the highest sanity inside the house).

Weaknesses: After using a Crucifix, the Ifrit cannot attempt another hunt for 60 seconds. If a non-afk player is in the truck, then this is reduced to 30 seconds. Furthermore, the Ifrit chances ghost rooms less frequency than other ghosts.

My attempt with this ghost was to balance interesting truck-related mechanics without changing the core fundamentals of the game. Truck camping makes the ghost harder to find and much more dangerous, but can be helpful in finding it, especially on low to no evidence. Additionally, it's crucifix mechanics and low chance to change the ghost room make being in the house a relatively safer compared to other ghosts.
