There are huts en route, but all but the first one (Brauneck) require some descent and re-ascent. This route descends to the shore of Kochelsee, before going to the train station, so bring swimming gear!
There is an optional detour to Glaswand for a bit of extra ascent (T4, description available here for the opposite direction, in German). Otherwise this probably is better considered a T3, as I very much doubt the descent from Rabenkopf on a forest path will be particularly dangerous, even if it is steep.
