Rubick build & guide (7.41)

Telekinesis

Rubick uses his telekinetic powers to lift the enemy into the air briefly and then hurls them back at the ground. The unit lands on the ground with such force that it stuns nearby enemies.

Aghanim's Shard: Allows you to target yourself or allies with Telekinesis. Throw distance is increased to 225 and throw delay is reduced to 0.5 seconds.

Fade Bolt

Rubick creates a powerful stream of arcane energy that travels between enemy units, dealing damage and reducing their attack and spell damage. Each jump deals less damage.

Arcane Supremacy

Rubick's mastery of the arcane allows him to have a larger cast range and bonus spell amplification.

Spell Steal

Rubick studies the trace magical essence of one enemy hero, learning the secrets of the last spell the hero cast. Rubick can use this spell as his own for several minutes or until he dies.

Aghanim's Shard: Upgrades stolen spells to their Shard version.

Aghanim's Scepter: Increases the number of spells that can be stolen to 2. Increases cast range, and upgrades stolen spells to their Scepter version.

Curiosity

Rubick gains 1 stack of Curiosity per level that grants him 1 base damage, 0.3% Buff/Debuff Duration, and 2 AOE Bonus. If Rubick sees an enemy Hero cast an ability within 1200 distance of him, he gains 2 Curiosity for 20 seconds. If an enemy Hero dies while Rubick has Curiosity from them and he damaged them in the last 3 seconds, he gains 1 Curiosity permanently.
