the main tool for this build is the moonlight greatsword. the armor i'd use would be the armor of the sun set, just to honor my old friend solaire. The rings i use are: The bellowing dragoncrest ring (25% damage increase to magic, and the moonlight greatsword does mostly magic damage.), the sages ring (increasing spellcasting speed is always good), the young dragon ring (further damage increase, though this isn't nearly as good as the bellowing Dragoncrest ring), and finally the untrue dark ring (fashion souls, this lets you look at the beauty of the moonlight greatsword when invading.). The staff that will be used for this is the Court Sorcerer's Staff, as it has the highest magic damage at 50 INT. For the spells, we have 5 attunement slots, so i will be using great farron dart, as it has a fast casting speed, and will be mostly used to finish people off when they run away. next spell is farron flashsword, again for its fast casting speed, and this spell give you a bit more melee coverage. next spell is homing crystal soulmass, this will be used to pressure opponents into making mistakes to avoid the damage that this spell can do. the last two spells are soul stream and crystal soul spear. these are purely for the damage that they have.
