Is mostly just an Int/Faith weapon. The Dex/Strength returns are minimal. One part of the skill, the beam, scales with only int and the fire fan only faith. The nice thing is how many buffs you can stack on top of one another with this build: Golden Vow, Howl of Shabriri, Tera Magicka + Magic Physick + Magic Ring, Rannala Cameo, Alexander Shard, Ritual Sword. It's going to be glorious.
If you want a true 4 stat weapon than look at Rellana's Twin Blades. Same deal with the Skill, but the weapon mostly scales mostly quality (Dex and Strength evenly)
