Class features, Sneak Attack, fighting styles, mastery effects, damage on a miss, special critical-hit effects, ongoing damage, resistance and immunity are excluded.

What Weapon of Warning does

Strength or 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 1d4 weapon damage averages 2.5 before your ability modifier and extra effects. Hit chance matters too: compare expected damage per attack rather than the die alone.
Finesse and 10-foot reach let a Dexterity-based melee character attack beyond the usual 5 feet. Positioning is its advantage; compare the damage die with other Finesse weapons below.
This item uses one of your attunement slots. Compare its benefit with the other items you want to keep attuned.

As long as this weapon is within your reach and you are attuned to it, you and allies within 30 feet of you gain the following benefits. Alarm. The weapon magically awakens each subject who is sleeping naturally when combat begins. This benefit doesn't wake a subject from magically induced sleep. Supernatural Readiness. Each subject has Advantage on its Initiative rolls. This is the Whip variant.

Properties

Finesse

When making an attack with a Finesse weapon, use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Reach

A Reach weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for Opportunity Attacks 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.
