血石魔法，一次也不行

Caudecus must be here somewhere! I suspect he's the culprit behind the Bloodstone explosion. I need to warn Canach and bring the minister to justice. Travel to the White Mantle colosseum. Check in with Canach. Overcome the ambush. Look for Caudecus. Defeat Justiciar Adrienne. Regroup with your allies. Continue the hunt for Caudecus. Confront Caudecus. Defeat the Jade Construct. Talk to Canach.

After some initial dialogue, the party will be attacked by a band of White Mantle members. After these, go through the gate. (It is easy to miss the small green star on the archway on the same platform where the ambush took place and it does not show up on your minimap. The mission instructions are simply 'Look for Caudecus' and after so much gliding in this zone, you may think you need to glide to the ground to search, but you will be killed if you attempt this). Once through the gate, make sure to dodge across the spiked floor traps. You will encounter Bloodstone Shards that attempt to drain your energy; use Counter Magic to negate the attack. Next, you will fight Veteran Bloodstone Elementals with a red shield that makes them invulnerable. To remove this shield, approach a Bloodstone Shard until it starts its energy drain, then use the Counter Magic skill but don't destroy Bloodstone Shard. Instead, walk around the Elemental, so that the path of the energy draining beam hits the Elemental, draining its shield. Once the Elemental shield is down, use Counter Magic again to destroy the Bloodstone Shard. Once you overhear some White Mantle voices, you will be fighting Justiciar Adrienne. The other enemies will keep spawning as long as the Justiciar is alive, so it's best to leave them to Marjory, Rytlock and Canach. She will be invulnerable to all damage until her shield is removed. To remove it, approach and attack the bloodstone shard in the center of the room until it fires a beam at you. Use the Counter Magic skill to enable you to move normally, then move toward the outside of the room so that Adrienne will be caught in the beam between you and the bloodstone. This will remove her shield and knock her down. Deal as much damage as you can before she renews it. If she gets the shield back, repeat the process until she's dead. Proceed up the stairs towards the stronghold. After confronting Caudecus, the final fight begins against a Subjugated Jade Construct. Similarly to the previous enemies, use the Bloodstone Shards and Counter Magic to remove shields as needed. In addition, the counter-magic beam deals high damage against the construct.
