Spell Mastery

Spell Mastery is an attribute and gameplay mechanic introduced in Total War: Warhammer III. As an attribute it indicates a spellcaster unit's spell intensity and as gameplay mechanic it increases the potency of certain spells.
== Description ==
How adept this unit is at casting spells
== Overview ==
Spell Mastery can increase the intensity of spells cast with Winds of Magic. Spells normally have an intensity of 100%, but spell mastery can increase this up to a maximum of 200%. At 200% spell intensity, the effects of most damaging spells and spells that buff or debuff a target will be doubled. Also while Spell Mastery can make many spells extremely powerful, not all spells will benefit from high intensity. Spell intensity does not affect the duration, range, cost or cooldown of any spells.
Before Update 5.0, access to spell mastery was fairly limited only to spellcasters with Greater Arcane Conduit. Any faction, the Wood Elf faction, and Kairos Fateweaver's personal army can each benefit from Mastery of Elemental Winds attribute. Each additional spellcaster with this attribute in an army increases spell mastery by 15%; an army with eight of these casters will achieve the maximum 200% spell mastery.
Following Update 5.0, Spell Mastery is now present in all spellcasters as an attribute. Please note that units with only Bound Spells do not count for Spell Mastery.

== Notes ==
A current bug with the UI does not show the effects of Spell Mastery on healing, most direct damage, and Winds of Magic recharge/reserve spell effects, but in-game testing'What does Spell Mastery do? - Unit Stats Explored' - Pariah Caste Gaming has shown that these spells are still benefitting from increased spell intensity.
