Archmage Support is a support gem that changes the linked spell's base mana cost to be equal to a proportion of your unreserved mana. It gives the skill added lightning damage based on how much mana was spent to cast that skill.

Skill functions and interactions

  • Supported Skills gain Added Lightning Damage equal to (#)% of Mana Cost... - Casting linked spells without triggers adds lightning damage based on mana cost of linked spell.
  • ...if Mana Cost is not higher than the maximum you could spend - Removes all lightning damage based on mana. While it is not possible to cast a spell that costs more than your current unreserved mana, IndigonIndigon

  • Vaal spells cannot be supported by Archmage. (This was possible shortly after the release, however.)

Damage Scaling - The base lightning damage scales with the base mana cost of skills. The base mana cost can be increased by having more total mana and increasing the mana cost of skills.

Mana Cost Scaling - There are multiple options for scaling higher mana cost. These options are not for scaling your total mana pool. See mana page for mana pool options.

    can raise the mana cost to it's highest functioning percent which is 100%, with the downside of the damage not working past 100% mana cost. This requires a delicate balance of mana spent recently and is generally harder to use than the other option. The following tips are broad and may not cover all details.
    • Never raise any spell cost over 100% or it will not gain lightning damage from archmage.
    • Try to spend the around the same amount of mana every 4 seconds. This does not have to be exact, but precision can help maximize the damage. The less skills with mana cost in your rotation, the easier this is.

      , more casts can be used without going over 100% mana cost. These skill will do maximum archmage damage when lavianga's duration expires or your mana maxes out. In other words characters temporarily do no archmage damage during the flask effect in order to do higher amounts of damage once the flask ends.
    • Indigon does not necessarily need the other options to raise it's mana cost, but they can still be useful. It depends on many factors.
