Quick Reference
Running This Encounter
The Archmage is a versatile spellcaster who should leverage their spell arsenal from range. Position them in defensible terrain with minions or environmental hazards to control the battlefield. Use legendary actions to cast cantrips or reactions to maximize survivability. Have them retreat or teleport when threatened, forcing the party to pursue through prepared areas.
Combat Tactics
The Archmage opens with crowd control or damage spells like Fireball or Hold Person before engaging in melee. They use Shield and Counterspell to neutralize threats, and cast Telekinesis or Dimension Door to maintain distance. When reduced to half health, they attempt to flee or summon allies rather than stand and fight.
Environment & Setting
An isolated tower, wizard's sanctum, or magical library filled with arcane wards and spell components. Include difficult terrain, magical traps, or conjured obstacles that benefit a ranged caster.
