I recently found out that the Lothric Knights can also drop a special crossbow.

The spear-armed knight can also drop the lothric knight greatshield.

While it is possible to parry most of the knight's attacks, they do have one slow overhead attack that can't be parried (tried several times with a parrying dagger, and could only ever get a partial). This makes for a very challenging enemy, seeing as the attack that -can- be parried is super fast, often causing you to react too early/late due to the threat of the slow overhead attack. It's strange that every single attack of a cathedral knight UGS can be parried, whilst this one has one that can't be.

Maybe I just need to git gud, but I'm pretty certain of these facts.

these guys can ***** off

Theres no mention here that they can be farmed for sunlight medals offline

Thought they also dropped sunlight medals?

While farming for a Lothric Knight Greatsword I had the greatsword knight drop a lightning gem, if that's worth noting on the loot as well.

Grand Archives Lothric Knights can buff their weapons with Crystal magic Weapon, as opposed to the Blessed Weapon of their earlier counterparts. This may be due to their proximity to the scholars and their studies.
