Advice on player's use of Umbral Leap into other rooms

[Kashyyyk]

How would you play out a wizard's use of Umbral Leap from Heroes of Shadow. They do not need line of sight for this power, and teleportation doesn't require line of effect. If the character sees the room that his comrades are in, further down a level and into the dungeon, and wants to leap there, how would you play this out? Just let it happen? Or, quickly cover the board to ask them how far they want to leap? They will catch on to this and meta-game of course. Would you count squares down as well, since the adjacent room was reached by a slide 30ft lower? Thanks

Assuming they have dim/dark squares in their room and in the destination room, and those squares are within 50 feet of each other (yes, vertical squares count, but remember that diagonals are "free"), then the teleportation works. If the character is seeing the room, then there isn't much to debate. If only the player can see the room (because the other characters are there), then it depends on whether/how the party can communicate with each other and how your table treats metagaming.
