Lich + Luna

Why this works

Pairing a defensive support with a carry seems like a safe bet, but the synergy between Lich and Luna isn't always straightforward. Luna wants to stand her ground to maximize Moon Glaive bounces in a fight, not necessarily kite backwards. While Lich’s Frost Shield is great for helping her do this, his other spells can be awkward. Sinister Gaze, for example, pulls enemies toward Lich, which can unintentionally drag a target out of Luna’s attack range or into a safer position. The slows are helpful, but they don't provide the hard, reliable lockdown Luna often needs to stick on a target.

In the laning stage, the duo can be quite strong. Constant Frost Blasts can easily set up kills for Luna. Later, a Frost Shield on a farming Luna makes her surprisingly resilient to ganks. The trouble can come in big teamfights. Luna wants to hit a primary target while her Glaives bounce, and Eclipse is strongest on isolated heroes. Lich's Chain Frost, on the other hand, wants the enemy team to be tightly grouped. While neither ultimate actively hurts the other, they don’t directly set each other up, leaving the outcome of fights down to positioning rather than a built-in combo.
