I feel like I recently saw something like this in another post but it got hijacked and taken off track.
@legionone had a great idea about adding consumables to echos to juice them along the lines of PoE does but with an obvious LE spin on things. There are endless ideas for what the modifiers could be and how they would assist players in spending less time grinding corruption in order to make the play drastically more challenging and fun. I think everyone can agree that as it stands grinding corruption is pointless and brings nothing of value.
I don’t know what kind of device it would be or how you would add consumables (non tradable and different in rarity) but it’s definitely an idea to look into for the sake of end game additions
