If you’re looking for the rarest units in Be The Final Boss, you’ll want to keep an eye out for Imperial Vanguard and Infernal Warden. Both are Secret-rarity units, making them some of the hardest-to-obtain and strongest units in the game. In the guide below, we will explain how to get Imperial Vanguard and Infernal Warden in Be The Final Boss, their stats, passives, and more.
How to Obtain Imperial Vanguard & Infernal Warden in Be The Final Boss
Imperial Vanguard and Infernal Warden are two Secret-rarity units introduced in Update 4 of Be The Final Boss, and you can only get them as rewards from Raids after dealing 30M DMG. The damage must come from you and your units, and damage from other players isn’t counted toward unit drops.
When Do Raids Happen?
Raids happen every 30 minutes, and you can join them 20 seconds before the timer runs out. You can see the time remaining before the next raid in the bottom right of your screen. Note that which unit you get depends on which raid boss spawns. The raid boss spawn is completely random, though.
