The 派对瓶 is one of the eight 药剂 that provide melee bonuses for the consumer. This particular flask provides a buff for 20 minutes that creates confetti when the player attacks with their 近战武器. The confetti created is purely aesthetic and does not provide damage bonuses.
- Besides crafting, there is a chance to get a Flask of Party from breaking a 猪龙彩罐, which can be bought during a 派对 from the 派对女孩.
- Using a drill while under the buff will make you ''shoot'' confetti.
- Since Flasks apply to all weapons that deal melee damage, it is possible to create large amounts of confetti using this flask with weapons such as 吸血鬼刀, 光辉飞盘s, 利刃手套 or the 腐化者之戟.
- 188.8.131.52：Buff duration increased from 15 to 20.
- 184.108.40.206.1：Sell price reduced from 50 to 5 . This was to fix an exploit for infinite money, since 5 Confetti cost 5 silver to buy, and when crafted into a Flask of Party, sold for ten times as much.
