This build is streamlined to take full advantage of Oakensoul.
Strengths: burst and pressure. Instead of an execute, we're making use of Power Overload and Crystal Weapon, weaving this heinous combination with a Major Breach-applying Shocking Soul, which has extra damage from the Sorcerer Class Mastery script. For our opening move, Crystal Weapon stuns from range, as long as we're sneaking and flanking. We have constant uptime on Minor Heroism from Oakensoul, so we have nearly constant access to Power Overload, which costs only 27 ultimate at stage 3 vampirism. Our mobility is excellent due to Streak and Swift jewelry. Darloc Brae + vampirism means sneaking is free and full speed, and we get our magicka back from Streaking extremely quickly thanks to the extra 15% recovery from Refreshing Shadows. Shattered Fate and 1 piece of Colovian Highlands General means our penetration is high enough not to require The Lover mundus, doing plenty of damage to tanky targets.
Weaknesses: we lack a strong HoT or multiple sources of passive healing in combat. We have a bit of passive healing from the Blood Magic passive every time we cast Crystal Weapon, and since we are running Darloc Brae – which benefits from Minor Mending – we have a 317-per-second (with Battle Spirit, assuming gold weapon and purple other set pieces), non-critting tick of healing if we're crouching, but that's usually only enough to offset a weak DoT. Otherwise, our main source of healing is burst heals from Contingency.
We're opting for extra penetration (Colovian Highlands) instead of health (Trainee chestpiece) with our leftover armor slot and making heavy use of roll dodge and invisibility to survive, since we don't have any additional crit resistance. Fortunately, with 6 or 7 pieces of well-fitted armor, a few stamina enchantments, Bewitched Sugar Skulls, and the Dynamic passive from being a Dark Elf, we end up with plenty of stamina to pull this off.
