Greater Arcane Conduit

Greater Arcane Conduit is a rare passive character ability introduced in Total War: Warhammer II which constantly increases the Winds of Magic power recharge rate and greatly increases its power reserves.

In-game description
"A strong mind is needed to channel the Winds of Magic. Those that have such a gift become arcane conduits - funneling the magical tempests to their cause."

Units

 * Ariel legendary hero
 * Lord Kroak legendary hero
 * Lord Mazdamundi legendary lord
 * Morathi legendary lord
 * Slann Mage-Priest lord
 * Teclis legendary lord
 * Necrarch Vampire Lord lord (campaign)

Strategy

 * Usually exclusive to the best legendary spellcaster hero and lord units in the game but also a couple of hero, lord and elite spellcasting units.
 * Acts like the uncommon Arcane Conduit active character ability but it is always switched on so no micromanagement needed!
 * In technical terms, it increases the power reserves by +30.
 * Supports aggressive spellcasting during battles and a magic-based campaign expansion.
