Professional Mode

*Not to be confused with Revenge Mode, which is permanently activated after defeating Doom Slime on both Normal, Expert, **Professional**, and Slayer worlds.*

**Professional Mode** is a difficulty mode introduced in the Spectra 10.21 update. Professional Mode serves as a greater difficulty of Expert Mode. It is permanently toggled by using the 666 item in Expert Mode or selecting it during world creation. This mode makes your gameplay an insane nightmare and brings far greater difficulty, bosses, enemy stats, power, loot, stuff, and much more. When activated, the message will appear in the chat saying "Your world is now Professional". It is suggested that players must choose Expert Mode first before challenging this mode, To challenge and defeat all of the bosses in that mode, Determination and power is key. It becomes a very huge nightmare by Slayer Mode.

Things are underlined **red** when seen on pages.
