Death Prophet + Lich

Why this works

Facing down both Exorcism and Chain Frost at once feels dangerous. The combination of slows from Spirit Siphon and Frost Blast can overwhelm an unprepared team, and Lich can keep a frontline Death Prophet alive with a well-timed Frost Shield. The main issue is that their ultimates have conflicting ideal scenarios. Chain Frost needs heroes to be tightly grouped for bounces, while Exorcism is perfectly happy to melt a single target or chase down spread-out enemies. Sinister Gaze can hold one hero in place, but the pair lacks a reliable way to lock down multiple targets and force a perfect setup.

This means the duo's success often depends more on the enemy's mistakes than their own execution. Early laning can be strong with repeated nukes, but securing kills is tough without a proper stun. In later teamfights, a disciplined opponent will simply split up to minimize Chain Frost's impact and focus fire either Lich or Death Prophet before they can get their full spell rotations off. The pairing isn't actively bad, it simply doesn't create a reliable advantage. You're mostly hoping the other team misplays into your damage rather than forcing a winning fight on your own terms.
