Change Enviroment Target Numbers

[needo]

I've been reading FREd as I seem to be doing more and more as my GM career begins to start in 1.5 weeks.

I was reading the portion on Change Enviroment. It says that the charecter chooses the target hex. However, it never mentions how much they should roll?

Do you have to make a successful attack roll? If so, what is the OCV/DCV?

Thanks!

Remember, FRED has an amazing index. Most of these questions can be answered in 10 seconds just by scanning the index.

Page 371 of the Index lists "Targeting a Hex (Combat Modifier)" as being on page 247 of the book.

Enjoy,
