Magic: Displayed damage is before applicable ability modifiers. Conditional extra damage applies only when its trigger and target requirements are met.
Calculator assumptions & rules
One attack against a creature. Natural 1 misses; natural 20 hits and doubles damage dice, not flat modifiers. Expected damage includes misses and critical hits. Advantage uses the higher of two d20s; Disadvantage uses the lower. Magic bonuses shown on the item are counted once.
Uses only the weapon’s ordinary hit and the listed on-hit extra dice, when enabled. Class features, Sneak Attack, fighting styles, mastery effects, damage on a miss, special critical-hit effects, ongoing damage, resistance and immunity are excluded. Check the full rules below for additional effects.

What Longsword of Sharpness does
- Strength can drive this martial weapon’s attack and damage rolls. Add your proficiency bonus to the attack roll only if you are proficient.
- The base 1d8 weapon damage averages 4.5 before your ability modifier and extra effects. Hit chance matters too: compare expected damage per attack rather than the die alone.
- Using two hands changes the weapon die from 1d8 to 1d10. Compare that damage gain with keeping a hand available for a shield or another task.
- This item uses one of your attunement slots. Compare its benefit with the other items you want to keep attuned.
When you attack an object with this magic weapon and hit, maximize your weapon damage dice against the target. When you attack a creature with this weapon and roll a 20 on the d20 for the attack roll, that target takes an extra 14 Slashing damage and gains 1 Exhaustion level. This is the Longsword variant.
