Living Portal (4e Power)

Living Portal	Warlock (Star Pact) Attack 19
A vacuous wormhole opens in your body, sucking in the beast in front of you, trapping it in the depths of space as it desperately tries to claw its way back through.
Daily Arcane, Implement, Cold, Necrotic, Radiant
Standard Action	Ranged 5
Target: One creature
Attack: Constitution Vs. Fortitude
Hit: Until the end of your next turn, the target is teleported into the depths of space, and takes ongoing 30 damage (Choose either radiant, or necrotic and cold when casting.) when the effect ends, take 3d6 damage, move the target into an adjacent square, and knock it prone. If the target dies during the effect, gain 2 healing surges and 6+2d6 hit points. If you die during the effect, the target chooses which square it appears in, and isn't knocked prone.
Sustain Standard: Spend a healing surge, instead of regaining hitpoints, make a Constitution vs. Will attack against the target. On a hit, the effect continues as normal. On a miss, the caster chooses to either end the effect, or sustain it and take damage equal to their Healing Surge value, and -2 to their Constitution until the end of their next turn.
Star Pact: Take no damage when the effect ends. Dark Pact: The ongoing damage is increased to 40, but can only be cold and necrotic. Fey Pact: On a miss with the Sustain attack, Constitution is unaffected.
