Spider Eye

A spider eye is a poisonous food and brewing item.

Spiders
Spiders and cave spiders have a $1/3$ chance of dropping a spider eye when killed by a player or tamed wolf, but not when killed by environmental damage (such as falling). The maximum amount of spider eyes is increased by 1 per level of Looting. The chance of a spider not dropping any spider eyes can be found using the formula. For example, Looting III gives a $1/3$ chance of not dropping any spider eyes. All other amounts have an equal chance of occurring.

Witches
Witches have a chance of dropping 0–6 spider eyes upon death. This is increased by 3 per level of Looting, for a maximum of 0-15 spider eyes.

Food
When eaten, a spider eye restores hunger points and 3.2 saturation points, giving a nourishment value of 1.6. It also applies a poison effect lasting 4 seconds to the player, causing damage, which reduces hunger/saturation by 12 points.
