Bigby's Icy Grasp questions

i say go off of logic here seeing as my experience with the game has shown me that it is based on logic.

you cant use your turn to hold the target for damage if you are just going to let go and grab him again. its a choice. either keep holding 1d8 or let go and attack another, separate, different target.

also to add to this fight does this dumb thing ever end?
it doesn't say it ends after an encounter so my friend just pulls it along with him through the entire dungeon

also also why cant monsters attack the thing. they just have to stand around while it demolishes them. That seems unfair to me.

hopefully im missing something.
I appreciate the help.

PHB p278: Unless a description says otherwise, you can sustain a power with a sustained duration for as long as 5 minutes.
However, you can't rest while sustaining a power, so you can't regain the use of your encounter powers or second wind until you stop sustaining a power.
