Cleric

Overview
Cleric is a healer whose job is to keep its allies alive and well. It's one of the recommended classes for beginners due to its straightforward supporting tools. However, unlike other beginner classes, it's rated high in meta and is frequently picked and banned.

The main reason for that is the Cleric's ult, Arise, which provides the extremely rare and powerful ability to resurrect a fallen ally. Arise can only be used within two seconds of an ally's death, so it's difficult to pull off on low levels of play when players aren't coordinated. However, with the coordination of pro players, Arise is a reliable and powerful tool which the enemy team must always play around.

In the Novel
When Yuel and Lars first met, they played against Taison and Gregory. Gregory played Cleric at the time, which was a nasty combo with Taison's Pirate. Normally, Pirate has a slow early game but can become very strong with stable farming. Therefore, with a Cleric to constantly provide heals and revivals to stabilize the Pirate's laning phase, it was challenging to beat these two in a 2v2.

Trever usually hunted the Cleric first to prevent Arise. However, that split his attention too much between the two enemies and he couldn't handle them both. To counter this duo, Yuel picked Paladin and told Lars to prioritize the Pirate. He showed there's no need to kill the Cleric first, it's enough to just silence Gregory with Justice Strike right as Gregory was about to cast Arise.

Later, it's shown that Paladin's Divine Shield also counters Arise. When Arise is activated, a fast ball of light is shot toward the target. Even though this ball has no attack properties, it's still treated as a "skill shot" by Divine Shield and is absorbed.
