Devour (standard, recharges when no creature is affected by this power)

Reach 3; +19 vs Reflex; 2d8+6 damage, and a Medium or smaller target is swallowed. A swallowed target is grabbed and restrained. A swallowed creature has line of sight and line of effect only to the behir, and no creature has line of sight or line of effect to it. A creature that escapes the grab is no longer swallowed and appears in a space adjacent to the behir. A behir can move normally while it has a target grabbed in this way. When the behir dies, the target can escape as a move action, appearing in the behir’s former space. Sustain Free: The behir sustains the grab, and the target takes 10 damage.
