Works well with...
- Frostbite provides the perfect setup for , a deadly combo as early as level 1. Later, it can be followed by Crystal Nova to provide an additional slow and ensure the full damage of Blade Fury.
- Arcane Aura provides much needed mana regen for Juggernaut as all his spells cost a considerable amount of mana. It allows him to repeat the combo Frostbite + Blade fury at any opportunity in the lane, while staying healthy thanks to . The aura stays relevant well into the late game.
- Frostbite provides great set up for Timbersaw's many abilities in all phases of the game, allowing him to place directly on top of an enemy hero, then following up with the rest of his combo.

- Many strength and agility heroes benefit greatly from Arcane Aura for the entire game, such as heroes like , , , , and so on. By having a source of mana regeneration via Arcane Aura, they can focus on other items that could benefit them more instead of having to buy an item for mana regeneration.
- Frostbite provides an instant, reliable disable that can be a good setup for unreliable spells such as , , , or .
- Any hero with a large, AoE disable works very well with Crystal Maiden (think , , or ), allowing easy setup for her ultimate, and ensuring that a decent duration of it is used before getting ended. Just be sure not to catch enemies' disables while using this tactic, otherwise both ultimates will be wasted!
