61.3 (LOA)

You strike two of the flowsteel panels and listen for the resonance of fifths or thirds as Tollin tweaks the size of each plate.

Choose two cards in the lithophone to strike, flipping them faceup. For each aspect whose value is the same on both of the struck cards, take an unused energy token of that aspect and place it above the lithophone. Then, flip both struck cards facedown, keeping them in the same order. If there is at least one energy token for each of the four aspects above the lithophone, the lithophone is tuned. Go to 61.4.

Clear Tollin again with  while HELPING HAND is attached to continue helping him tune the lithophone.
