Chapter 17 (Church) - Tips and Tricks

Deploy a High Mobility Unit to Get Chests

Deploying a fast unit can minimize the time spent obtaining the chest. Prolonging the fight will cause enemies to swarm your team so time is of the essence.

Capture and Leave Respawn Tiles

You only need to step on the respawn tiles to make enemies stop from respawning. No need to make your units stay and make them help in the battle!

Bring a Unit with Knightkneeler

Your units should be strong enough to survive an attack from the Death Knight but that doesn't mean the Death Knight is now an easy foe. Defeating him immediately is a must and the Knightkneeler Combat Art does this right.
