Sentries

The Sentries are an Act 1 elite encounter consisting of 3 Sentry enemies, each with 38-42 HP. They act in a fixed alternating pattern: odd-numbered Sentries Beam (9-10 damage to player) while even-numbered ones add Dazed cards to your discard pile, then they switch roles. All three Sentries share the same action cycle, so their combined output is consistent and predictable.

The Sentries are particularly dangerous for deck-cycling builds because the Dazed cards they add are Unplayable and accumulate rapidly, slowing your card draw and cycling efficiency. AoE damage cards are extremely valuable in this fight to hit all three simultaneously. Killing one Sentry reduces their combined output by a third. Decks with strong AoE like Whirlwind, Cleave, or area poison effects can clear the Sentries efficiently.
