Ambitious arcanists such as you aren’t bound by morality. Mostly acolytes of Vecna these mages’ ambitions lead them to the use of blood magic and other dark arts, the most powerful of these mages were known to use not only arcane but also divine magic to achieve their goals.

Blood Channeling

When you choose this arcane tradition at 2nd level, you are able to use your own depleted life essence to channel your magical abilities. Whenever your current hit points are below your hit point maximum, you can use your own body as an arcane focus.

In addition, when casting a wizard spell that requires a costly material component, you can forego the component by taking 1d10 necrotic damage per 50 gp of the cost of the component (minimum 1d10). This damage can’t be reduced in any way. If this damage reduces you to 0 hit points, the spell fails but the spell slot is not expended.

Sanguine Burst

Also at 2nd level, you learn how to weave your life force into a spell you cast, boosting its intensity at the cost of your vitality. Whenever you roll damage for a spell you’ve cast of 1st level or higher, you can choose to take necrotic damage equal to the spell’s level to reroll a number of the damage dice up to your Intelligence modifier (minimum one). This damage can’t be reduced in any way, and you must use the new rolls.

Arcane Revelations

At 6th level, you may add two spells of your choice that do not appear on the wizard spell list to your spellbook. A spell you choose must be of a level you can cast, as shown on the Wizard table, or a cantrip. The chosen spells count as wizard spells for you, though cantrips chosen this way do not count against the number of Cantrips Known on the Wizard table.

Arcane Versatility

Beginning at 10th level, you can copy any spells from spell scrolls that you find into your spellbook, even if these spells do not appear on the wizard spell list. For each level of a non-wizard spell you copy into your spellbook, the process takes 4 hours and costs 100 gp. This increased cost represents the difficulty of translating other schools of magic into your own personal notation system. Copied spells count as wizard spells for you, and once you have spent this time and money, you can prepare these spell just like your other spells.

Master Of All

At 14th level, you may add two more spells of your choice that do not appear on the wizard spell list to your spellbook. A spell you choose must be of a level you can cast, as shown on the Wizard table, or a cantrip. The chosen spells count as wizard spells for you, though cantrips chosen this way do not count against the number of Cantrips Known on the Wizard table.

Hereafter, every time you gain a level in the Wizard class (starting with 15th level), one (but not both) of the spells that you add to your spellbook may come from a different class's spell list, though you are free to learn two wizard spells if you prefer. Your spellcasting is now bounded only by your own interests and imagination.
