5. Quick Gameplay Tips
- The Purification Combo: You can deal heavy damage to enemies by using Purifying Flames multiple times in quick succession. If you cast Fate's Edict first to provide magic resistance to an ally, you can follow up with Purifying Flames to heal them without dealing damage to them. Alternatively, use Purifying Flames twice on an enemy for a massive burst of magical damage.
- False Promise Timing: Do not wait for an ally to reach 10% health to cast False Promise. The spell removes negative status effects upon activation, so it is often better to use it pre-emptively when a key ally is being focused by CC or burst damage. The delayed healing doubled at the end makes this one of the strongest "save" abilities in the game.
- Purge Positioning: Fortune's End can be a reliable setup for your team. By channeling the bolt, you can hold an enemy in place for a significant root duration. Coordinate with your team so that you channel the purge as an enemy is attempting to flee, ensuring they are rooted in a location where your allies can easily follow up with their own disables.
