What are the Fetters of Omniscience?

The Fetters of Omniscience is a mid-to-late game item in Dota 2 that provides a significant boost to your hero's mana pool, mana regeneration, and cooldown reduction. It's an excellent choice for heroes who rely heavily on casting spells frequently, allowing them to stay in the fight longer and have a greater impact. This item not only enhances your hero's sustainability but also enables more aggressive playmaking, making it a staple for many support heroes and some core heroes alike.

Key Stats and Benefits

The Fetters of Omniscience offers a compelling set of stats that make it a valuable addition to any hero's inventory. Let’s break down what this item brings to the table:

+20 All Stats: This provides a well-rounded boost to your hero’s attributes, increasing strength, agility, and intelligence. This translates to more health, armor, mana, and attack speed, making your hero more resilient and effective in various situations. The additional stats contribute to both survivability and damage output, making it a versatile upgrade. Having a balanced stat increase is crucial for heroes who need to scale effectively into the mid and late game. This ensures that your hero remains relevant as the game progresses, providing consistent value in team fights and skirmishes.
+20% Magic Resistance: This significantly reduces incoming magic damage, making you more resistant to enemy spells and nukes. Magic resistance is crucial for surviving intense magical burst damage, especially in team fights where enemy spellcasters can quickly turn the tide. This bonus can be the difference between life and death, allowing you to stay in the fight longer and continue casting spells. Magic resistance is particularly important against heroes with high magical damage output, such as Zeus, Lina, and Crystal Maiden. Equipping the Fetters of Omniscience can help you mitigate their impact and survive their burst potential.
+15 Mana Regeneration: This substantial mana regeneration ensures that you have a steady supply of mana to cast your spells frequently. Mana is a crucial resource for most heroes, especially those who rely on their abilities to deal damage, control the battlefield, or provide support. With increased mana regeneration, you can cast spells more liberally, allowing for more aggressive playmaking and strategic spell usage. This bonus is especially valuable for heroes who have high mana costs or need to cast spells repeatedly during team fights. It ensures that you won't run out of mana at critical moments, allowing you to continue providing value to your team.
+25% Cooldown Reduction: This reduces the cooldown time of your spells, allowing you to cast them more often. Cooldown reduction is a powerful stat that can significantly increase your hero's effectiveness. By reducing cooldowns, you can cast spells more frequently, leading to higher damage output, more crowd control, and better utility. This allows you to have a greater impact in fights and push objectives more effectively. This bonus is particularly beneficial for heroes who have impactful spells with long cooldowns. Reducing these cooldowns allows you to use your key abilities more often, making you a formidable presence on the battlefield.

Crafting Recipe

To craft the Fetters of Omniscience, you'll need the following components:

Kaya: Provides +16 Intelligence and +10% Spell Amplification. Kaya is an essential component for spellcasters, boosting both their mana pool and damage output. The spell amplification is particularly useful for heroes who rely on dealing magic damage, making their spells hit harder and more effectively. The added intelligence also helps with mana sustain, ensuring that you have enough mana to cast your spells frequently. Kaya is a cost-effective item that provides a significant boost to your hero's magical capabilities.
Refresher Shard: Adds a one-time use active ability that resets the cooldowns of all your items and abilities. The Refresher Shard is a game-changing component, allowing you to use your spells and items twice in quick succession. This can be incredibly powerful in team fights, enabling you to unleash devastating combinations or provide crucial support multiple times. The one-time use nature of the Refresher Shard means it should be used strategically, often to initiate fights, secure kills, or turn the tide of a battle. It’s a versatile item that can be utilized in a variety of situations.
1000 Gold Recipe: The recipe cost adds a bit to the overall price, but it's well worth it for the combined benefits of the item. This recipe cost ensures that the Fetters of Omniscience remains a significant investment, reflecting its powerful capabilities. The gold spent on the recipe is a small price to pay for the substantial advantages the item provides.

Combining these components results in the Fetters of Omniscience, a powerful item that enhances your hero’s mana pool, mana regeneration, magic resistance, and cooldown reduction. The item’s recipe reflects its mid-to-late game status, making it a significant investment that pays off in sustained spellcasting and survivability.
