Combat and Tactics
This knight has a passive evade skill and two attacks. One will send a ball projectile towards the player, dealing Cursed Damage. After getting hit with the projectile, the players hits will mostly be misses for a short time. The second attack is when a player comes close to the Knight which causes it to hit them with his shield.
Hollow Knights of the Cursed are wearing the Set of the Bulwark which is Portal Knights' armor sets and a Hollow Mask of the Overlord which is a vanity item. This might suggest that they were Portal Knights in the past.
