Strength

Strength is an effect which increases attack power.

Effect
Increases melee damage by × level $$. Negative levels decrease melee damage, with attacks being ignored entirely if damage would be 0 or lower.

$$, melee damage under the effect Strength level n can be found by the recursive formula $$damage_n=floor(damage_{n-1}\times1.3+1)$$where $$damage_0$$is the base attack damage with whatever weapon or tool is used to attack, and $$damage_n$$is rounded down to the nearest integer with each recursion.

$$floor$$means to round down to the nearest integer, for example $$floor(3.14159)=3$$and $$floor(-123.456)=-124$$.

Immune mobs
Withers and ender dragons are immune to Strength. While not immune, any mobs that cannot attack are unaffected by Strength.
