The 血液瓶 summons a pet 蝙蝠 when used. It grants the player the Pet Bat 增益 that lasts until the player manually cancels the buff or dies. The pet bat flies around the player, dealing 2-4 damage to enemies it happens to touch, and can travel through all blocks. When a player is in a body of water, the bat will fly above it like any other type of bat. When the pet bat gets too far from the player, it can fly back instead of shooting back with clouds behind it.
The Vial of Blood is an uncommon drop from 吸血鬼矿工s. It can also rarely be obtained from 金箱s.
- The Pet Bat is the only 蝙蝠 which can travel through blocks.
