Thanks everyone for helping me out with this ruling, & for the link to "Previous discussion" I read though most of it. The 5 foot step out of DT was also an interesting debate...
So I get very clearly that moving into Difficult terrain costs you the extra movement. But does moving Out of difficult terrain into a regular square cost you extra movement as well? Or just a regular 5 foot cost? Hope someone sees this And is kind enough to answer; thanks.
