Entangling Force is great when it works but in dungeons I feel like it's mostly useless since it doesn't work on bosses, that's why I keep Enfeebling on the bar most of the time rather than Entangling.
What powers do you use in dungeons imivo? I'm assuming Tabbed Chill Strike, Steal Time, Conduit of Ice and Ray of Enfeeblement. I'm stuck between Conduit of Ice and Shield for the last encounter spot.
