'''Weakness''' is an [[effect]] that decreases melee damage. It is required to cure [[zombie villager]]s.

== Effect ==
Melee damage inflicted by the affected entity is reduced by {{hp|4}} × level {{in|java}}. Negative levels increase melee [[damage]] dealt.

{{IN|bedrock}}, melee damage under the Weakness effect can be found through the equation <math>BaseDamage\times0.8^{level}+{0.8^{level}-1\over0.4}</math> where <math>BaseDamage</math> is the ''default'' attack damage with whatever weapon or tool is used to attack.<ref group=note>Background for the new equation: https://docs.google.com/document/d/1GtZ9ceTfVGbEkKkbZAfzpKKGk2FQ0FwmeUyw5ja14B8/edit?usp=sharing</ref><ref group="note">To find the damage when [[Strength]] and Weakness are applied at the same time, first calculate the damage with the Strength formula, then plug that in as the "<math>BaseDamage</math>" in this Weakness formula.</ref>

Attacks with a damage of 0 or lower would be ignored entirely, however {{in|bedrock}}, the use of enchantments such as [[Sharpness]] still allow damage to be dealt.

This effect is also used to cure [[zombie villager]]s, preceding the [[golden apple]].

The effect can be removed by drinking [[Milk Bucket|milk]]. {{IN|education|bedrock}} when education options are enabled, drinking [[elixir]] also removes weakness.
