Templar Impaler

The Templar Impaler is a miniboss which guards the altars in the second quest in the Darkest Dungeon. He takes 2 actions per turn, one of which is typically a Revelation attack. His other action will be spent on one of his remaining attack abilities, all of them equally dangerous.

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. Alternately an Antiquarian can be brought without the trinket and she can use "Protect Me" skill to make another unit guard her.
 * You'll also want to bring a lot of Antivenom - the Impaler can apply heavy blight. Similarly, Holy Water can help prevent you from being blighted in the first place.
 * 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.
 * 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.
