# Pentagram System

Open your inventory with the **\[I]** or **\[V]** hotkey and you can locate your pentagram area. Each pentagram camera has 1 to 5 slots for adding errtels. The **‘5th Slot’** of the pentagram must be unlocked with the **EXPANSION SCROLL OF RADIENCE SLOT** item, it can be obtained from boss drops or created. When you create the character, you will receive the starting pentagram that you can place in your special slot.
