Warp

Warp is a side effect of going "too far" with your research. Things like the flesh golem and the bucket of liquid death are examples of this. Warp is the warping of the mind that comes from such things. Currently, all warp is permanent and the only remedy for it is a temporary reduction for 30 minutes in the form of Purified Bath Salts.

The forms of warp include
 * Headaches, rather unintrusive
 * Strange whispers telling you things *this one can be rather useful because you gain primal research aspects when this happens
 * Sun-scorched: your gamma turns up to 11 and your brightness becomes even brighter while any form of light can set you on fire. Having some sort of fire resistance at all times once this level of warped is reached is a must
 * Unnatural hunger: a craving for rotten flesh that can last upwards of seven minutes if no flesh is eaten. Having a stack of flesh on you at all times at higher levels of warp is recommended.
 * Deadly Gaze: your gaze hurts all entities seen by you. Can be helpful at night to clear out a large horde from your second story window or harmful in the nether if received in the middle of a pack of zombie pigmen.
 * Blindness: the entire field of view becomes dark, with only things two blocks in front of the player being visible, does not last very long even at high levels of warp.
 * Blurry Vision: same as blindness but blurry instead of dark
 * Mind Spiders: a horde of tiny spiders spawns around the player with only one health. Any type of armor equipped will keep the player from taking a lot of damage and an open hand can take out all the spiders in one hit.
 * Something stirs in the mist: The area around you is covered in fog, only for you, and an eldritch guardian spawns and starts blasting you. Simply kill it and move on, the fog will pass in time. The guardian has 50 health and about the same in runic shielding. Decent armor and weapons are recommended before reaching this level of warp, which is not too far into Thaumcraft.
 * You feel oddly drained: This one is in a competition for most-annoying with sun-scorched as it gives the player flux-flu, which increases vis cost for the duration of the debuff. It passes in time, but it completely stops any creation of Thaumcraft toys to play with.
