Gordon can’t remember the exact specifics but she got the Blasphemous Blade after the Rykard fight and loved it so much she based her build on that. Faith was 60 (the first soft cap) plus with a talisman that gives that a boost also. Quite late in she respecced to beat a particular boss who was weak to lightning and discovered that 40 vitality was really good as you can take two, sometimes three heavy hits from some bosses and survive. So when she went back to her Blasphemous build she tweaked it to keep the vitality at 40.
Impressed me so much that I’m respeccing my second playthrough Thor Candles build to take advantage of it. I always get by with a glass cannon, but later game that leads to frustration; eg I’m trying to do the Fire Giant just now, which can one shot even middling vitality and can be very difficult to dodge due to how wide his early attacks can be.
The end result was that with the right talismans and pre fight rituals (potions, buff spells) she was doing 2 - 2.5k per hit with the Blasphemous Blade (the left trigger skill, scales purely on faith). Which is substantial, more than just chip damage on bosses.
She also has Radahn’s great bow with Radahn’s Rain on the left trigger which MELTS big mobs and the final boss (one of the talismans vastly increases the max range of arrows and a lot of spells) someone aggroed the Elden Beast and from a distance she used Radahn’s Rain to take chunks of the health bar. It varies depending on how still the boss is at the time but the best hit took about a sixth off his health bar.
It was quite something to see. 🙂
