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 Dragon Slayer does

Strength can drive this simple weapon’s attack and damage rolls. Add your proficiency bonus to the attack roll only if you are proficient.
The base 1d6 +1 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.
The normal range is 30 feet and the maximum is 120 feet; attacks beyond normal range have Disadvantage. The calculator lets you model the attack mode separately.
The extra damage is conditional: Target is dragon. 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. The weapon deals an extra 3d6 damage of the weapon's type if the target is a Dragon. This is the Javelin variant.

Properties

Thrown(Range 30/120)

If a weapon has the Thrown property, you can throw the weapon to make a ranged attack, and you can draw that weapon as part of the attack. If the weapon is a Melee weapon, use the same ability modifier for the attack and damage rolls that you use for a melee attack with that weapon.

Weapon mastery

Slow

If you hit a creature with this weapon and deal damage to it, you can reduce its Speed by 10 feet until the start of your next turn. If the creature is hit more than once by weapons that have this property, the Speed reduction doesn't exceed 10 feet.

You need a feature, such as Weapon Mastery, that unlocks this property for you.
