Greatest Story Never Told

[Magnesium02]

on riddle 4 I've tried Sunstone earrings, nothing happen tried malachite rings and bracelet nothing...this shit is pissing me off and for what they give you its more trouble then it's worth

What is the two letters he tells you to solve the equation for?

so frustrated! i bought a sun stone ring, i talked to the guy that gave me the list, i equipped it.

and the little "you've done the thing" symbol is on my freaking map but all Hart says is something patronizing about "I may not be the most educated man, but even *I* know arithmetic uses numbers not letters"

Do I need 2 rings or just the one???/

You only need one, and you need to have it equipped while talking to the Message, not the NPC.
