ME: Uproot the sign and read it.

10 (⚄⚄) + 2 (ARM lvl) + 1 (the sign has no roots) = 13

You successfully uproot the sign.

It's... blank?!

ME: Throw sign off edge.

You are about to throw it on edge when your cousin spots something. It has writing on the other side, dummy!

You read it and then throw it off the edge. Kinda ironic, considering its message.
