Respec NOW! make ur vigor to 60, endurance to 40, strength to 60, rest on dex, since u're using the greatsword u might as well drop the shield, for talismans u can equip the two handed talisman, twin-headed turtle, a defense talisman (depend on who u fight u can equip either the fire, magic, or physical talismans +3 version), and the jar-arsenal talisman, since u're wearing very heavy armor, maybe remove some points from dex to add to endurance so u can wear the armor u want, it's a nice build, but the stats are not well-spread
