Luna + Razor

Why this works

Pairing these two cores seems like it should be a straightforward damage plan, but the reality is more complicated. The synergy is mostly theoretical. Razor can use Static Link to drain a key target's damage, making it much safer for Luna to stand her ground and right-click. Eye of the Storm also shreds armor, amplifying all of Luna's physical output. In return, Lunar Blessing gives Razor a small boost to his own attacks. These interactions are certainly helpful, but they don't combine into a single, overwhelming threat on their own.

In a real game, their timings can be at odds. Razor hits a major power spike in the mid-game and wants to force fights, running at enemies to leverage his damage drain. Luna often prefers to use that same space to accelerate her farm and hit her own later item timings. Since they lack a hard stun between them to lock down a target for an Eclipse, they can end up playing separate games on the same map until much later. The synergy is opportunistic, not something you can build a whole draft around.
