Notes from author
This build is meant to emulate the Greek goddess Hecate. This build is very versatile with its high Int/Fth at the expense of low vitality.
It is able to use the majority of spells/miracles and all pyromancies. Good spell choices include: Dark Bead, Pursuers, Crystal Homing Soulmass, Crsytal Souls Spear, Crystal Magic Weapons, Great Magic Shield, Sunligh/Darkmoon Blade, Wrath of the Gods, Great Magic Barrier, Great Comustion, Black Flame, Power Within.
This build's amour choice is mostly for fashion but can be optimized with the Dusk Crown and some poise.
Obsidian Greatsword provides great damage and is buffable but can be swapped for the Moonlight Greatsword, Velkas Rapier (fast roll with current setup) or the Moonlight Butterfly Horn (fast roll with current setup). Each weapon has its own use case so you can swap as the situation requires.
Other important gear not shown is a +5 Ascended Pyromancy Glove, Tin Crystallization Catalyst (for damage boost when needed), Ring of the Suns First Born (for miracle damage) and the Seance Rings which can hold single cast spells such as Power Within or Sunlight Blade and be swapped out after cast.
Build works well shield-less (move talisman to shield hand) and works best when equipment swapping to fit your current needs.
I would advice to put any additional levels into Vitality, Endurance or Intelligence (only if you push it to 50 to use White Dragon Breath).
