Self-Destruct (arcane, aura, evocation) When a clockwork sphinx is reduced to 0 Hit Points, it collapses and emits a steady ticking sound. At the beginning of what would've been its next turn, the sphinx explodes into a 20-foot emanation of shrapnel, dealing 6d10 piercing damage (DC 26 basic Reflex save). An adjacent creature can cancel the self-destruct sequence by succeeding at a DC 26 Thievery check to Disable a Device at any point before the sphinx explodes, but on a critical failure, it explodes immediately.

Pounce [>] Frequency once per round; Effect The sphinx Strides and makes a Strike at the end of that movement. If the sphinx began this action hidden, it remains hidden until after the attack.
