Potions: This build doesn't require specific potions.
Food: Ghastly Eye Bowl or Solitude Salmon-Millet Soup if you need health

Rotation:
- Apply all DOTs (Damage Over Time skills) and buffs
- Any time all DOTs are ticking use Concealed Weapon as your spammable
- Every 5th light attack (When the icon changes), use Merciless Resolve
- Whenever a DOT or buff falls off, reapply it. Prioritize Barbed Trap and Degeneration. Keep carve at 3 stacks by reapplying it before it runs out.
- Use Incapacitating Strike every time you have it.
- When a boss reaches 25% health, your spammable becomes Impale.

Inner Light is what we call a "bar buffer". Meaning we never actually use this skill, it's simply there for the slotted bonusses and/or the skill-line passives it provides for us.

Flex options:
Your survivability should be great on MagBlade, since Merciless Resolve heals you and the Shadow Barrier passive will give you permanent uptime of Major Resolve.
If you do need additional protection, replace Dark Shade with one of these skills: Siphoning Attacks or Harness Magicka.
Using one of these does mean your damage is lower.

Weapon choices:
This build runs Dual Daggers on the front bar and a Greatsword on the back. Prefer using staves? Use a flame staff and make these changes:
Stampede --> Unstable Wall
Carve --> Inner Light (Or a flex skill)
