Entangle and sickening entanglement for a start. Plant growth is something you can set up well in advance if need be. Those generally require you to be in the wild somewhere of course.
Frost fall + rime spell works anywhere as does slowing mud, and both are worthwhile. Ice spears (possibly + rime spell) is also useful. Explosion of rot looks good though I haven't used it. Control winds can be amazing in the right situation.
