Recall Knowledge DC 50 (arcana)
Disable DC 40 thievery (master) or DC 35 religion (master) four times to obliterate each of the four key runes. A DC 45 thievery (legendary) check (or breaking the lattice) stops the clockwork's movement and prevents it from resetting, but doesn't stop its current activation.

A complex clockwork of bright metal and delicately carved gemstones, the lattice's interlocking gears begin to whir as golden runes glow across its surface.
