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 the mana cost of that skill.

Skill functions and interactions

• Supported Skills gain Added Lightning Damage equal to 75% of Mana Cost... - Casting linked spells adds lightning damage based on the mana cost of the 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, can raise the mana cost beyond the base after the spell is already cast.

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

• Eldritch Battery allows you to spend energy shield before mana. The skill still gains the added lightning damage based on mana cost, even though you're not spending mana to cast the skill.

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

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

• Use high mana multiplier support gems. Use Fevered Mind. give a 50% increase in mana cost compared to 2 handed weapons with no support gems built into the item.

• can raise the mana cost to its 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 around the same amount of mana every 4 seconds. This does not have to be exact, but precision can help maximize the damage. The fewer skills with mana cost in your rotation, the easier this is.
  • will make skills cost no mana. While this makes Archmage do no damage during the flask effect, it also prevents Indigon from raising the mana cost. When using dynamic spells with a duration like Blade VortexBlade VortexSpell, AoE, Duration, Physical

These skills 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 to do higher amounts of damage once the flask ends.
  • Indigon does not necessarily need the other options to raise its mana cost, but they can still be helpful. It depends on many factors.
