honestly, I have had a bunch of knight related ideas recently and it has mostly been coincidence, in fact this thread is multiple knight related ideas
Stats change
I thought long and hard about this and decided the best change for knight to be not super against what he was, the change would be -10 def to max, however there would also be +5 spd and +5 atk to max, he would still have the most def of melee classes, having extended def like pally and def giving abilities like warrior and balances out the change with a slight atk and spd upgrade
ST set bonus
This change is simple, wearing the full ST set give +15 hp/mp, and +3 atk/def/spd/dex/vit/wis
This gives a small boost for wearing all the ST old tops
Snakeskin shield change
Dazes and slows instead of a stun
Gives 3 dex, 3 spd, and 4 def as it’s stat bonus
inspiration of idea to @JohnMH
Shield change (and quiver)
in a different thread
That is about all
