Minecraft wiki entry for Strength, associated text: In Bedrock Edition, melee damage under the effect strength level x can be found by the recursive formula damage(x) = floor(damage(x – 1) × 1.3 + 1) where damage(x) at (x = 0) is the base attack damage with whatever weapon or tool is used to attack, and damage(x) is rounded down to the nearest integer with each recursion.[1]
