Fight Fear near a wall
Razorfen Kraul’s quilboar casters fear and silence. In an open corridor, one Fear can bring the next pack. Tremor Totem and Fear Ward help, and wall positioning limits the path before either spell is needed.
Fear, bat riders, and Charlga
Fear: tank with the back to a wall whenever the room gives you one. An open pull lane gives Fear room to reach another pack.
Bat riders: they patrol and join from above. Check the ceiling before declaring the pack finished.
Charlga Razorflank: interrupt Chain Bolt and destroy the totems immediately.
Pull the casters backward
Line-of-sight every caster pack and fight around the corner. A corridor gives Fear room to turn one cast into a larger pull. Start that discipline on the first pack.
Use the wall before the pull
One Fear in open space can reach the next room. Find the wall before the pull.
