Correct Persistent Tail usage?

[OSEZNO]

PS Oops, a player wanted to know that since it says "creature" you could even put this on an ally that you knew was going to move and it would still work, right?

Conceivably they could, if they had cover or concealment against that ally?

Otherwise it would say enemy instead of creature.

As someone said above, you COULD use the power twice during your turn if you want to give up your standard action and then have a choice of two targets to trigger on, though you can obviously only actually trigger on one of them. Note too that you can trigger on ANY square of movement, so you don't have to use it on the target's first square of movement for instance. This could be handy if for example the target moves out of your line of sight. Say they go around a corner at some point in their move you could wait for that to happen, trigger on that square of movement, and that way stay out of sight. This brings up the final point, as soon as someone moves to a spot where they don't have cover they are going to lose their hidden status. The DM might rule in a non-combat situation that the target isn't looking your way, but in a fight you're not necessarily hidden as you move.

Only thing I'm worried about now is, that once our DM knows someone has put Persistent Tail on a target, he won't *ever* move that target again.

That may not be such a bad thing either. At-will immobilize? That's got some control potential.

Unless you're just slapping it on a target in the hope of getting a less restrictive stealth check only against that target (and it's fairly rare that you can't get full cover or concealment if you can get cover or concealment) then chances are you want to react to a move by an opponent - and if he doesn't move, he's not doing whatever it is that you dread. Like walking up to you and smacking you in the mouth for instance.
