Recall Knowledge DC 39 (arcana)
Disable DC 40 thievery (master) to wipe away the faint runes scratched on the floor without activating a blade, or DC 43 religion (master) to utter memorial prayers to Gorum to rob from the trap its violent energy

A section of ground thrusts up to form what looks like a mountain in which a sword has been impaled, and then the sword lashes out to stab at someone nearby. A successful DC 15 religion check to Recall Knowledge is enough to note that the hazard looks very similar to Gorum's religious symbol; any character who is at least expert in Religion notes this automatically.
