Skeleton Knight

Skeleton Knights are a kind of boss in Silver Dungeons. Similar to the recently-added Skeleton trap horses, Skeleton Knights are simply a Skeleton riding a Skeletal Horse. However, the similarities end there. Instead of spawning with an Iron Helmet and an enchanted bow, Skeleton Knights spawn with full Chain armor, an iron sword, an iron shovel, and a bow. In terms of enchantments, the sword and shovel both have Sharpness I, and the Bow always has Power I and Punch I. The horse itself has Iron Horse Armor. Unlike Skeleton trap horses, the Skeletal Horse that the Knight rides actually will engage in combat with the player, similar to Spiders in Spider Jockeys. Its attacks deal 6 damage (3 hearts) on Easy, 7 damage (3.5 hearts) on Normal, and 9 damage (4.5 hearts) on Hard. The Skeleton's sword deals 6.5 damage and its shovel deals 5 damage. Shots from its bow can deal between 2 and 6 damage on Easy and Normal, and between 2 and 7.5 on Hard. Besides its armor and equipment, the Knight has three times as much health as a normal Skeleton, at 60 (30 hearts). Its armor provides 39.2% defense.

AI
The Horse and the Skeleton alternate between dominance for control. The horse charges the player, causing high knockback and dealing its damage. If this happens, the Skeleton is likely to remain in close quarters. In close quarters, the Skeleton alternates between its Sword and its Shovel at random. The skeleton's melee attacks have a 0.7 second delay on average, causing its shovel to do less damage. The Skeleton often retreats to a distance if hit and will use its bow. The boss is not considered defeated until both the Skeleton and the Skeletal Horse are dead. The Skeleton has a high chance of dropping its items.

Non-Boss
In Gold and Diamond dungeons, spawners can spawn non-boss versions of these. They have ordinary health, and a more simplified AI.
