So you want long lines of hit attempts? I know I wouldn't. I've been known to miss many times in a row...
Please give me a page number for this. As far as I know, any number of free actions can happen in a round.
Now Planar Gateway is a free action triggered by starting in the gateway or moving adjecent to it. Where does it say it can be triggered only once?
If you don't want long lines of hit attempts, then don't, slide the target 2 and stop mucking about...
There is nothing concerning about Grease...
The page number for free action does not equal at-will is not needed. At-will, encounter, and daily are frequency of use keywords for powers. Free-action, standard action, move action, and minor action, are the types of actions needed to trigger the use of said power
So an encounter power, that takes a free action to activate... is not an at-will power.
it is still an encounter power. NOT at will.
I can't clarify this any further...
Free actions can be taken any number of times in a round, however the Planar Gateway Attack is an
encounter power, and no matter how many times you use a free action to activate it, it will only work once per encounter.
