IT'S CLOBBERIN' TIME: The Thing can use Quake. Give the Thing a power action; he can move up to his speed value and then as a free action either (1) use Quake or (2) make a close combat attack.

i know this is kinda a given but for the fact it doesn't say thing must still break away, i am guessing it is inferred?

Yes, as per the regular rules, if he starts his movement next to an opposing figure, he must break away first. Nothing in the special power would alter that.

Yup, doesn't say anything about automatic break away, or give him a power that allows it, so he must roll!

Yes, you must still break away.
The only way i can think of to make it easier is to give him the Slippery feat - a Slippery Thing should be feared!

Not touching THAT with the proverbial 10' pole...

That's what she said

A YELPing Slippery thing?

I don´t know you... but this? this is not for kids guys
