Is anyone else finding that the Heilde Knight sword is basically a better version of the Drake Sword? Now people may argue that the Fire Longsword is this effect but the Knight sword is actually more powerful than the Fire Longsword and lightning is resisted by a grand total of 1 boss in the entire game.
Both make the early game a hell of a lot easier due to high damage output even without upgrading them and both are fairly easy to obtain right near the start of the game.
Now the main point of divergence from the Drake Sword is that upgrading the Heilde Knight Sword is actually worthwhile. The Drake sword gained maybe...50 points of damage when upgraded, was far harder to find materials for to upgrade and generally got outclassed by upgraded normal weapons by the midpoint of the game once you had decent stats.
By contrast the Knight sword just keeps getting better and better, it's a Quality build weapon much like the Zweihander and at +10 does over 300 damage per swing, considering that the heavier hitting weapons only do about 200 damage more, require a vastly bigger amount of stamina to swing but are better if you can't hit the boss more than once before having to back off while the Knight Sword shines when you can just wail on a boss, putting the lower stamina requirements pre swing to better use.
