Tremble

 is a miscellaneous item in Fallout: New Vegas.

Tremble is a devastating neurotoxin that causes uncontrollable spasms and tremors. Arguably the most effective Poison in the game, Tremble causes violent shaking fits so bad that weapon use is rendered extremely difficult if not impossible. Accuracy becomes moot when one can't stop shaking, and even melee weapons suffer slowed swing rates as the unfortunate struggles with their uncooperative body to swing their weapons. In short: It causes a massive, 50-point reduction in every weapon skill the subject has (other than unarmed) for 20 seconds. It also deals 40 damage over these 20 seconds. Whilst Tremble is the least dangerous Poison in terms of damage, but is highly desirable due to its secondary effects; it can quite literally take a considerable bite out of the offensive of virtually any Human, Super Mutant, or Ghoul foe. Note, however, that it is virtually useless on muated wildlife, giant bugs, or Feral Ghouls, all of whom use unarmed attacks.

Like all venoms, it can be applied to any melee weapon (including thrown weapons) to allow you to envenom a target on a successful hit. Note that one dose of poison lasts for one strike or thrown projectile only.
