及时之雨

Respond to the disturbance at Fort Salma. Travel to Fort Salma in Kessex Hills. (Secure the western gate.) Secure the Western Gate Rescue and escort the Seraph to the fort. Meet up with Kasmeer and Marjory inside Fort Salma. Secure the arrow cart on the eastern wall. (Use the arrow cart to secure the eastern gate.) Destroy the Mordrem attacking the eastern gate. (Defeat the Mordrem boss.) Mordrem Thrasher Regroup with Belinda.

The instance starts with Fort Salma's western gate being attacked by Mordrem, so fight them off. After the gate is secure, Belinda will ask you to rescue and escort a small group of Seraphs to the northwest. Meet up with Kasmeer and Marjory back in Fort Salma, finding them just inside the gate to your left. Travel via the northern wall (you can take the southern wall if you want, but there are more foes) to avoid the in the center, and find the arrow cart on the eastern wall. After you have secured the cart, use it to destroy all the Mordrem attacking the eastern gate. Try to ignore the Mordrem attacking your platform and focus on the ones below. After the gate is secure, a Mordrem Thrasher boss will spawn. It starts off invulnerable to damage, inside a shield of vines and green smoke. You'll need to escort Marjory's Bone Fiend minions up to the shield, which the fiends can destroy. At that point you can attack the Thrasher; rinse and repeat the process a few times. Kasmeer's reflect barriers can protect you against the Thrasher's spore projectiles, if needed. Once the Thrasher is dead, head west through the fort to regroup with Belinda.
