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 Oathbow does
- Dexterity 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.
- The normal range is 150 feet and the maximum is 600 feet; attacks beyond normal range have Disadvantage. The calculator lets you model the attack mode separately.
- This weapon needs two hands when you attack, so a wielded shield conflicts with that attack setup.
- This item uses one of your attunement slots. Compare its benefit with the other items you want to keep attuned.
When you nock an arrow on this bow, it whispers in Elvish, "Swift defeat to my enemies." When you use this weapon to make a ranged attack, you can utter or sign the following command words: "Swift death to you who have wronged me." The target of your attack becomes your sworn enemy until it dies or until dawn 7 days later. You can have only one such sworn enemy at a time. When your sworn enemy dies, you can choose a new one after the next dawn. When you make a ranged attack roll with this weapon against your sworn enemy, you have Advantage on the roll. In addition, your target gains no benefit from Half Cover or Three-Quarters Cover, and you suffer no Disadvantage due to long range. If the attack hits, your sworn enemy takes an extra 3d6 Piercing damage. While your sworn enemy lives, you have Disadvantage on attack rolls with all other weapons. This is the Longbow variant.

Properties
Ammunition(Range 150/600; Arrow)
You can use a weapon that has the Ammunition property to make a ranged attack only if you have ammunition to fire from it. The type of ammunition required is specified with the weapon's range. Each attack expends one piece of ammunition. Drawing the ammunition is part of the attack (you need a free hand to load a one-handed weapon). After a fight, you can spend 1 minute to recover half the ammunition (round down) you used in the fight; the rest is lost.
Heavy
You have Disadvantage on attack rolls with a Heavy weapon if it's a Melee weapon and your Strength score isn't at least 13 or if it's a Ranged weapon and your Dexterity score isn't at least 13.
Two-Handed
A Two-Handed weapon requires two hands when you attack with it.
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.
