Modifiers

Rune Arcane: Dispellable with any dispel.

Notes:

• Reduces the cooldown/replenish time of all spells and items.

• Affects cooldowns of active and passive abilities.

• Visually reduces the cooldown of Tranquil Boots, but does not affect it.

• Does not affect Cloak and Dagger and Drunken Brawler's certain crit/evasion timers.

• The cooldown reduction is not updated dynamically. Only abilities cast while having the buff get their cooldowns reduced.

• Besides the mana cost reduction on items, all reductions are reflected in the ability tooltips.

• Only affects the activation cost of spells. Mana cost over time is not reduced.

• Stacks multiplicatively with the cooldown reduction of Octarine Core.

• The buff is applied to invulnerable and hidden units.

• The buff of multiple Arcane Runes does not stack, but refreshes the duration instead.
