Arcane Rune

Reduces cooldowns by 30% and mana costs by 40%.

Cooldown Reduction: 30%
Mana Cost Reduction: 40%

Notes:

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

• Visually reduces the cooldown of Tranquil Boots (Active), but does not affect it.
• Does not affect Cloak and Dagger​ and Drunken Brawler's certain critical/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.
