WX-78

WX-78 is the fourth unlockable Character (960 XP, see Experience for more information on how to unlock it). WX-78 is a self-sustaining automaton who hates all living creatures. It can eat stale and spoiled Food without Health or Hunger penalties. However, food penalties that occur even if the food is not spoiled still take effect. (Such as Monster Meat .)

WX-78, being a robot, will take damage when it is in the Rain. Umbrellas can't migitate this. The amount of rain does not matter and WX-78 will always take 1 Health point of damage every 2 seconds. The damage will not stun him when taken, similar to Fire damage. This damage can be negated if the player has an Umbrella equipped. When taking rain damage WX-78 emits light due to sparks flying off its body. This provides enough light to prevent the Charlie from attacking it, but WX-78 will suffer great sanity loss from the darkness.

Special Powers
WX-78 has two Special Powers (added in Strange New Powers update)

SYSTEM OVERLOAD
The first power is his SYSTEM OVERLOAD ability. When WX-78 is out in a thunderstorm he has a chance to be struck by lightning and will actually draw in the lightning much like a Lightning Rod. This will cause it to instantly regain its health, gain a speed boost, and emit an amount of light similar to a Torch. It will also prevent it from freezing for the duration of the effect. WX-78 will lose 33 Sanity when initially struck. This power is also initiated immediately after teleportation with the Telelocator Staff, due to the subsequent lightning strike in the immediate area. The SYSTEM OVERLOAD will last roughly 1-2 days.

Upgrading
The second power is WX-78's ability to consume Gears to upgrade itself. When eating a Gear WX-78 will recieve an upgrade for its maximum Sanity, Health, and Hunger.

WX-78
WX-78 can upgrade itself by eating gears.

The max amount of Gears that can be consumed to gain stat upgrades is 15. However WX-78 can still consume gears to gain the initial 60 Health, 50 Sanity and 75 Hunger that WX-78 always receives when consuming gears. This means for WX-78, Gears can be used as a sort of non-spoiling superior version of Jerky, although it should be noted that Gears are not renewable.

The amount of each upgrade increase varies a little bit from upgrade to upgrade to keep the numbers balanced and even - except for health, which has a steady +20 increase on each upgrade. The stepped upgrade effects on sanity and hunger can be seen in the table below.

Trivia
