Bosh Rash is a Challenge Stage in Vampire Survivors featuring enemy waves of the Bosses from all Stages with increased health. For every minute that elapses, all enemies' HP multiplier increases by ×0.1 with no cap. Additionally, this map contains two pressure plates that appear every 30 seconds. First, the blue pressure plate is characterized by an hourglass symbol, and if players trigger this mechanic in Vampire Survivors, the stage will skip time to the start of the next minute. The other pressure plate is red and is indicated by a skull symbol. Stepping on this pressure plate will respawn the wave of Bosses currently on the field. These two plates will stop appearing after the 9:30 mark.
The Bosh Rash Challenge Stage in Vampire Survivors is rather strange in that it spawns items outside the arena, which is inaccessible to the player character. More specifically, Floor Chicken ×2, Orologions ×2, Nduja Fritta ×1, and Rosary ×1 are Pickups that appear outside of the borders of the map. Furthermore, all passive Stage Items, excluding Torrona's Box, spawn outside the arena.
To collect these useful yet out-of-bounds items in Bosh Rash, Vampire Survivors fans must activate an Arcana known as Mad Groove (VIII). This Arcana automatically causes all Stage Items, Pickups, Experience Gems, and light sources to move towards the player character every two minutes. Accordingly, Mad Groove (VIII) is regarded as the only legitimate means of accessing the oddly placed items in Boss Rush. Players can unlock this particular Arcana by reaching the 31st minute in Mad Forest.
