Just started DS3 a few days ago (only played an hour or so at a time due to work schedule lol) and finally had a free day to go ham. My start was Knight class (for the purest build experience), and when I encountered the Lothric Knight, I immediately wanted this armour set. So I spent a solid eight hours farming it and levelling up in the meantime.
I'm SL 32 now, with enough Vitality to midroll with full set + shield. Picked Fire Gem as my gift, and am currently rocking a +3 Fire Longsword to go along. Should I work Vitality higher to wield the Claymore, or focus on building strength/vigour for now?
