How To Unlock Yellow Sign

Introduction

The Yellow Sign is a relic that can be found on the stage Holy Forbidden. Once collected, it unlocks the passive items Silver Ring, Gold Ring, Metaglio Left, and Metaglio Right, making them available as floor pickups in the majority of stages. Additionally, the Yellow Sign is required to unlock certain secret characters and events.

Unlocking Yellow Sign

To unlock Yellow Sign, you must enter the Holy Forbidden stage, a hidden area accessible after surviving 14 minutes in the Moongolow stage with a standard character (any character that isn't secret). Additionally, you need to defeat the special angel-like boss of the stage, called Trinacria.

After defeating Trinacria, you will be teleported to Holy Forbidden. From there, simply follow the path east until you come across the Yellow Sign relic on the floor. Pick it up, and you will have successfully unlocked it.

Unlock Through Spell

If you prefer, you can unlock Yellow Sign using a cheat code. Simply access the Secrets menu, which you can find in the main menu if you've unlocked The Forbidden Scrolls Of Morbane. Then, enter the code 'ihaveseenitihave­seenitihaveseeniti­haveseenitihaveseenitihavese­enitihaveseenit' and you will have Yellow Sign unlocked.
