Acolytes have very little defense, however they can hit extremely hard with both bludgeoning and piercing (whichever is weaker) so they can pose a challenge.

It is best to approach with a high damage output as even when they block, very minimal damage is absorbed. The sooner you can kill them the less damage they can do. Ensure to approach every encounter in as full health as possible as a landed critical hit can occasionally do in excess of 25 damage.
