(I am sorry for my bad english)

It would be a perfect skin for a Halloween version of one of the existing bats but if statistics are needed it could be this:

Pros:

+When hit and thrown, the bottle gives the poison-like effect found in mannpower on contact and does damage even underwater.
+fast recharge
+Doctors cannot remove it as easily as bleeding.
+Lasts longer (a few seconds longer)
+Recharges quickly

Negative effects:

-You are more vulnerable to weapons that cause fire.

the projecticle has a mad milk/jarate type explosion that gives:
monochromic vision
mini crits
regular crits (only from your bat)
slowness
bleed (direct hit)
with a damage penalty when needed


only 1 of these option if it wasnt clear

+ Gain 15% of base health on kill
+ Has a 50% of slowing down enemies.
+ Coated enemies take mini-crits
+ Extinguishing teammates reduces cooldown by -15%
+ Players heal 45% of the damage done to an enemy covered with milk.
+ On Hit with Buildings: Disables it for 3 sec. for Lv. 1, 5 sec. for Lv. 2, and 10 for Lv. 3.
- Honorbound: Once drawn sheathing deals 90 damage to yourself unless it kills. Projectile that hits enemies and buildings and assist related to it does not count.
- This weapon deploys 100% slower
- 80% max primary ammo on wearer
- Deploys 50% slower
- -45% explosion radius
- Launched jar shatter on hit with enemy projectiles and shatters friendly projectiles on hit
- NO RANDOM CRITICAL HITS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

+Gain 20% higher ♥♥♥♥ size on hit
-On miss: Lose your ♥♥♥♥ for a month
-You get cyberbullied for using it

+ You are able to throw an acid that weakens the enemy, granting a crit on that player for the melee weapon
- Heals the enemies for 100hp (can overheal) and clears the acid after 10 seconds
- No random Crits

my concept
pros

+ alt fire throws bottle on hit enemies take +150% melee damage
+15% movement speed and jump height while active

cons
-50% holster speed
no double jump
-25% firing speed

Pros
throw bottle on alt fire
on hit bleed
cons
enemies that hit you regain health

The High Stakes
Level -15 Bat

+ Alt Fire: throw the holy water to apply both Jarate and Mad Milk to a single target
+ Gain 15 max health
- deploys 15% slower
+ deals 4x Dr. Acula, The Count Tavish, and Voodoo-Cursed Souls

+Holy Water gives the target 100% vulnerability to melee damage. The effect lasts for 10 seconds.
+The effect duration increases during Halloween (15 seconds total)
-Deploys slower
-Attacks slower
