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
- Every third ability, cast Stalking Blastbones
- Any time all DOTs are ticking use Ricochet Skull as your spammable between Blastbones.
- Replace your spammable with whichever DOT is falling off, but keep casting Blastbones every third ability. Prioritize Barbed Trap and Degeneration. Keep carve at 3 stacks by reapplying it before it runs out.

Your rotation will basically look like:
Skill --> Skill --> Blastbones --> Skill --> Skill --> Blastbones, repeat

Flawless Dawnbreaker and Inner Light are what we call "bar buffers". Meaning we never actually use these skills, they are simply there for the slotted bonusses and/or the skill-line passives they provide for us.

Flex options:
If you need additional protection, replace Degeneration with one of these skills: Summoner's Armor, Spirit Guardian or Harness Magicka.
Using one of these does mean you're losing out on Major Sorcery, so you'll HAVE TO RUN SPELL POWER POTIONS to make up for this. If you do this also swap out Inner Light for Deadly Cloak (And Mystic Orb if you're using Inner Light on the back bar).

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)
