=== Calculating Ability Duration ===

Multiple sources of Ability Duration stack '''multiplicatively''', not additively:

<math>\text{Total Ability Multiple sources of Ability Duration stack '''multiplicatively''', not additively:} = 1 - (1 - R_1) \times (1 - R_2) \dots</math>

'''Example:'''

With '''{{ItemData|{{#vardefineecho: Item1|Magic Carpet}}|BonusAbilityDurationPercent}}''' from {{ItemIcon|{{#var: Item1}}}} and '''{{ItemData|{{#vardefineecho: Item2|Diviner's Kevlar}}|BonusAbilityDurationPercent}}''' from {{ItemIcon|{{#var: Item2}}}}:

# Convert percentages to decimals: {{ItemData|{{#var: Item1}}|BonusAbilityDurationPercent}} to {{#vardefineecho: Item1Duration|{{#expr: {{#replace: {{ItemData|{{#var: Item1}}|BonusAbilityDurationPercent}}|%|}} / 100}}}} and {{ItemData|{{#var: Item2}}|BonusAbilityDurationPercent}} to {{#vardefineecho: Item2Duration|{{#expr: {{#replace: {{ItemData|{{#var: Item2}}|BonusAbilityDurationPercent}}|%|}} / 100}}}}.

# Subtract from 1: (1 - {{#var: Item1Duration}}) = '''{{#expr: 1 - {{#var: Item1Duration}}}}''' and (1 - {{#var: Item2Duration}}) = '''{{#expr: 1 - {{#var: Item2Duration}}}}'''.

# Multiply the differences: {{#expr: 1 - {{#var: Item1Duration}}}} × {{#expr: 1 - {{#var: Item2Duration}}}} = '''{{#vardefineecho: CombinedItemDuration|{{#expr: (1 - {{#var: Item1Duration}}) * (1 - {{#var: Item2Duration}}) round 4}}}}'''.

# Subtract from 1: 1 - {{#var: CombinedItemDuration}} = '''{{#expr: 1 - {{#var: CombinedItemDuration}} round 4}}'''.

# Total Ability Duration bonus is '''{{#expr: (1 - {{#var: CombinedItemDuration}}) * 100 round 1}}%''', not {{#expr: ({{#var: Item1Duration}} + {{#var: Item2Duration}}) * 100 round 1}}%.
