I love your ideas! Your second way of writing for him definitely sounded better
Here's some various suggestions and things for the Knight:
Rewards:
Paladin's Armor: Vanity set, has the appearance of the Paladin enemy's armor
Paladin's Greatsword: A broadsword, around the same damage as The Horseman's Blade, same color scheme as the Paladin's Hammer, otherwise just a basic sword
Trusty Lance: Summons a Noble Steed (Horse in battle armor) to ride on. When riding, you carry a lance, which deals some serious knockback to enemies, and can be used to Joust with other players.
Quotes:
"Back in the good 'ol days, I was adventuring into the Hallow with my fellow knights and my king, when we were attacked by pixies and unicorns! We lost our king, and we don't know what happened to his sword either" (Definitely needs to be edited to make it fit ith the character
)
Quests:
Wyvern - When I was just a lad, before I served me King, I saw a dragon! A dragon I say! Me family didn't believe me, but I know what I saw! Bring be back its tooth, so I can prove I was right!
