Templar Impaler

Templar Impaler is a mini boss-type enemy guarding altars in the second quest in the Darkest Dungeon. He takes 2 actions per turn, one of them usually to use Revelation, bringing protective trinkets is pretty much mandatory. Other action will be spent on one of his 3 attack abilities, all of them equally dangerous. Bringing as many Antivenoms as possible might be a good idea as they apply heavy blight.

Strategy

 * Bringing all 3 Talismans of the Flame is required in order to survive this fight. Your party member who is left unprotected from the devastating Revelation should be guarded by a MAA or Houndmaster.
 * When fighting the double Templars, it would be recommended to focus down the Warlord first, as it is the one with the less amount of HP.
 * Using Holy Water before each of the Templars fight can prove to be a life-saver against their high Blight damage.
 * If you manage to stun them after each revelation attack, you can really minimize the amount of damage they deal to almost none if the Revelation lands on a protected hero.
 * If you can displace the Impaler to the back row you will be safe from the Stinger Stab, which deals massive Blight damage. Considering their mediocre Move Resistance, this can be a pretty feasible task.
