Dazzle + Sniper

Why this works

Holding high ground or securing Roshan relies on keeping your main damage source alive. Dazzle enables this for Sniper with a well-timed Shallow Grave, giving him precious extra seconds to fire away when enemies finally break formation and dive him. The slow from Poison Touch can also help Sniper create a bit of distance, while Shadow Wave offers some light healing to offset chip damage during a siege. It’s a simple plan: keep the glass cannon firing, and Dazzle has the one tool that lets him do that under direct threat.

In practice, the value of this duo emerges during mid-game teamfights when Sniper has damage items and becomes the primary target. The entire fight can swing on whether Dazzle can apply Grave in time. However, experienced enemies will play around this. They can focus Dazzle first, knowing he is also fragile and immobile, or use chain-disables on Sniper to run out the Grave's duration. Since both heroes are easy to catch out, a coordinated jump can often neutralize the synergy entirely before it has a chance to matter.
