sword build with high defense
http://underrail.info.tm/build/?HgcPAwcDBAcAUADCoAAAAFUyAADCoMKgRkbCoAAAAAAyS8KgMShVDcKMFsKZBsKLEsKOwqpSwoFLwo3Cs9-_don't pick Armor Sloping if you want to make good use of armor penalty.
Armor Sloping is useless on this build because you have have low AGI and no Dodge/Evasion,
you're a tank in this build so better go all out on the defensive side.
you can reduce the CON and increase AGI if you want evasion instead and pick Armor Sloping.
i personally like DEX to do crits, but if you think it's too high, lower it by 2 or 3 and increase the CON even more,
or at least replace the "Increased DEX" with "Increased CON" instead.
and if you want to use the Sormir Skaerder Sword, replace unneeded feats with Vile Weaponry, Taste for Blood, and Eviscerate.
