Contingent Glyph (abjuration, occult) A hieracosphinx has an innate magical defense similar to a contingency. When they take a specific type of energy damage (varying by the individual sphinx), they can use their reaction to have the glyph cast haste on them. The glyph is then dormant for 1 week. A critical success to Recall Knowledge about a particular hieracosphinx (30 or higher on the check) reveals which damage type triggers the glyph.
