Palace Guard

The Palace Guard is a boss added as part of the Eternal Palace update. They are found within the Eternal Palace and Ancient Basin and were minions of the Pale King, summoned to the Palace from the Crystal Peaks. They are nearly identical to the early game boss Crystal Guardian that was fought in the Crystal Peaks.

Location
Two Palace Guards can be found outside the Eternal Palace at the Palace Gates. The Knight receives help from Hornet and Dung Defender during this fight. When killed, the gates to the palace open.

Another set of Palace Guards can be found in the area where Broken Vessel was fought in the Ancient Basin. They will only appear here if the original set of Palace Guards, as well as Lost Kin, have been defeated. They drop from the ceiling as a surprise encounter if the the Knight revisits the arena.

Behavior and Tactics
The Palace Guards, as stated above, are fought in sets of two. They have three attacks, most of which are similar to the Crystal Guardian’s attacks. Unlike the Crystal Guardian, the Palace Guards do not have a armored head, and therefore can be nail-bounced on. When one of the Palace Guard is killed, the other will let out a boss roar similar to the Oblobbles fight. However, the other Guard will rage and his attacks remain the same. If the first Palace Guard is killed by Hornet or Dung Defender in the Eternal Palace fight, than the roar will not occur
 * Leap: A guard will leap from their place to a short distance to move around the arena.
 * Laser Beam: A guard will point it’s hand at the Knight and shoot a large laser beam. Similar to beams within the Crystal Peaks, they start of harmless and enlarge, becoming dangerous for about a second. Only a single Guard can use this attack at a time.
 * Crystal Spikes: A Guard will launch up to three damaging spikes at the Knight. They will move straight directly across the arena, shattering as it touches a wall.
