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 Giant Slayer 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 +1 weapon damage averages 5.5 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.
- The extra damage is conditional: Target is giant. Enable it only when that condition is met; otherwise compare the weapon’s ordinary hit.
You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. When you hit a Giant with this weapon, the Giant takes an extra 2d6 damage of the weapon's type and must succeed on a DC 15 Strength saving throw or have the Prone condition. This is the Warhammer variant.
