Runes of Power

The Runes of Power are a mystical resource in the world of Dota 2.

Description
For uncounted aeons, the origins of the Runes of Power remained unknown and unknowable to all who attempt to divine their origins. Even the gods who can comprehend mysteries beyond mortal knowledge know little about them. They are mysterious to all but an aspect of the Primordial Consciousness named Zet, who can casually create these runes out of thin air. All of these runes are forged from the most fundamental magic, which is possibly the elements of Quas, Wex, and Exort (see the Runes section below for the reasoning) Despite the crystalline appearance, runes are implied to be immaterial or ethereal objects.

When collected with an enchanted Bottle, the runes seem to enjoy going in the bottle for unknown reasons.

Pugna claims that all magics have their source in the Nether Reaches. Aether (also known as void and nothingness) is an essential ingredient in the arts of the arcane, including the Runes of Power. This may be supported by Void Spirit who states that these magical runes come from the void  or contain the essence of the void itself.

Arcane
The infuses the user's abilities with its arcane energy, reducing the costs of using magic. The has what appears to be an Arcane Rune attached on top of its handle, granting the item its revitalizing properties and the ability to help its user bear the weight of arcane expenditure.
 * It has the ability to restore the user's connection to their respective power source. For instance, the Arcane Rune restores Windranger's connection to nature's elementals, and it restores Void Spirit's connection to the void, even when he is away from the its embrace. This means that the rune can adapt to different users' powers or power sources, hinting at a universal power source.
 * Apparently, using an Arcane Rune reveals the "kingdom of the arcane" to the user. This may be the same "kingdoms of magic" mentioned in Rubick's lore.

Bounty
The grants gold, but the gold it bestows is said to be different from normal gold, hinting at the gold's mystical or extraordinary properties.

Double Damage
Once it is consumed, the can infuse the user with power that allows them to hit twice as hard.

Haste
The red imbues the user with increased speed. The speed even extends to their heartbeat, suggesting that it even makes the internal body go faster.
 * The younger Carl claims that he can sense the presence of Wex in this rune. If Carl can sense traces of his magic in this rune, then it is possible that the fundamental magics that forges these runes may very well be his Quas, Wex, and Exort. This may be further supported by Zet (who can create these runes) warning the Invoker that his sorcery meddles with powers that he can't comprehend.

Illusion
The creates two identical copies of the user who are under their progenitor's control.

Invisibility
When used, the will turn its user invisible. A single Invisibility Rune can work on two separate entities at once.

Regeneration
The infuses its user with its regenerative power. In some cases, it would seem that the rune itself does not heal the user, but it taps into whatever source of their healing they have to heal them instead. This includes: The rune even works on those of the void or aether element, allowing it to restore the pure nothingness within the Void Spirit or renew the void-shadow flesh of the Enigma. It can even restore the powers of those who consume this rune. Despite this immense power, it is said to have its limits. One of these limits might include its inability to regenerate Clinkz's lost flesh.
 * Leshrac and his Impurities
 * Lion and his demonic rage/revenge
 * Omniknight and his god, the Omniscience
 * Earthshaker and his Earth element
 * Abaddon and the Font of Avernus
 * Oracle and his prophecies
 * And many more heroes being healed by their source of power...

Water
holds the element of water, which is said to be the essence of the material plane. The effects of this rune in the lore is unknown.
