The two-hand animations are very similar to Demon's Souls

Does anybody know what is the best overall straight sword for strenght build?

From experience, the three best straight swords are the Red Rust for pure damage on a high strength build, The Fume for range on pure dex or dark builds, or the drake keepers on quality or power stance builds for its above average in every aspect flexibility.

longsword ftw

Full slashing movesets are what really hinders most of this weapon class. Bad design choice, their AR/counter dmg isn't high enough to break the game if they got stab attacks anyway

a shame there aren't that many good looking SS, all the love got to the weeb*****

Oh boy i miss balder swag sword

You can use these weapons on the offhand with a larger slower weapon in the mainhand to speed up many attacks. Let's say you were using a great club mh and longsword oh, if you were to press L1 and then R2 you'll notice that the R2 comes out very fast compared to the usual windup the attack has.

I found that the Fire Longsword is missing from this list. Second bonfire of Forest of Fallen Giants, Below the Scaffolding and in a burning tunnel is a fire lizard, if you run and open a door to get in a room there will be a chest that has the Fire Longsword.
